P&W | EViDENT is a group of young dentists that focus on lecturing ideas and innovation to others In order for a better communication, we use digital works to explain the concepts. Most importantly we not only target the dentists as audience, but also the patients too. We are also proceeding the philosophy of evidence-based dentistry, especially in fields of periodontics, prosthodontics and dental implantology. The team was planned over a year (2014-2015) and collected data of needs from undergraduate dental school students and dentists with clinical experience. We share our ideas, our studies, great articles, information of all kinds of dental courses for every dentists and students to get the latest news and discuss for our own protocols.

E7 dental e-publishing is one of the online/ paperwork of P&W | EViDENT. The publication contains 7 topics per volume in different aspects of dentistry. It is more like a magazine with both dental research and the enjoyment of living. Including topics of lecturing, practical sessions, photos galleries, lifestyle sharing and etc. It is designed for dentists to have a brand new thinking in the academic field.

Authors could be anywhere! E7 epub. is an open sharing work which everyone could subscribe and we are happy to have more and more dentists, professors, students and etc. to join us work. We are more than welcome to have hear your work experiences, knowledge and ideas, and encourage you to share with no limitation. Lastly, we welcome and kind of suggestions that will help us improve

From Chairman In our constantly changing world, our team P&W | EViDENT stands to the future of being the milestone of dentistry information sharing. It’s our pleasure to gather information and knowledge to enhance our development of the publication; without changing, there will not be any innovation, creativity, or incentive for improvement. Those who initiate change will have a better opportunity to manage the change which is inevitable.

Development and change is not a simple act. There is no single development in e i ther technology or management . Everything in life is related. Our idea of improvement and development is through sharing experiences and knowledge unselfishly. We think everything in life is a chain. In order to become better you need to help others.

Introduction The term “Osseointegration” has been established widely when describing the concept of how does the dental implants “seal/ implantation” to the bone. And of course, we could never forget the great work Swedish Dr. Per-Ingvar Brånemark (1929-2014) achieved for us.1

In early 1950’s, he first began conducting experimenting with titanium implant chambers to study blood flow in rabbit bone, discovering that the bone had integrated so completely with the implant that the chamber could not be removed. Brånemark called the discovery “Osseointegration.” 1

In the mid 1960’s, he began his first successful experiments on humans. Indeed, his first patient went on to live another 40 years with the original implants still in place and functioning well.1

At first very few fellow scientists took Brånemark very seriously and there was little

acceptance of osseointegration as a viable treatment. In Sweden he was even openly ridiculed at scientific conferences. Eventually an emerging breed of young academics started to notice the work being performed in Sweden and at a Toronto Conference in 1983 the worldwide scientific community finally began accepting Brånemark's work.1

One of well-known, and excited work from Dr. Brånemark was hanging the mandible of dogs, ( B i o m e c h a n i c a l C h a r a c t e r i z a t i o n o f Osseointegration: An Experimental in-vivo Investigation in the Beagle Dog) proofing the osseointegration of titanium implants and the mandible, which the forces/ loading contains one mature dog’s weight.2, 3

The original definition of “osseointegration” by Brånemark (1969), provided by Albrektsson et al. (1981) suggested that this was “a direct functional and structural connection between living bone and the surface of a load carrying implant.” 4 The description then was applied by Newan e t a l . in Car ranza ’s C l in ica l Periodontology. (Elsevier) Another, clinical def ini t ion was provided by Zarb and Albrektsson (1991) who proposed that osseointegration was “a process whereby clinically asymptomatic rigid fixation of al loplast ic mater ials is achieved and maintained in bone during functional loading,” 4 which the discussion including the bone analysis from the work of Lekholm & Zarb Classification.(1985) 5

These days, The concept of osseointegration has opened a new new emerging field of science, the biological surface science and

stresses its importance in the field of alloplastic materials and dental implants.6 which biomechanical forces are one of the scientific research topic to traced down the response and the maintenance of the osseointegrated forces between the dental implants and the bone.

Evident-based Results

Although the concept and the clinical trail/ reviews of osseointegration reveals highly efficient, the real result of the biomechanics of new bone is still a consideration. Whether the bone is closely bonded to the surface or just a simple “stuck” on the titanium surface. The following clinical photos has shown some evident of the osseointegration.

50yrs more, a male patient came for the surgical removal of dental implants (posterior more, more or less 3yrs) due to the fracture of the screw inside the abutment. (occlusal loading fracture) Saving the implant was

difficult since the fragments of the screw was blocking the pathway of the remaining thread, piezo-surgical remove is proceeded.

As the dental implants is removed, the bone on the titanium surface was magnificent. The density of the bone/ bone grafts was intact, and the bone was difficult to separate even using the curettes. Nevertheless, we could not identify the force amount between the 2 different materials, the bonding is compact accurately. Fixation was achieved and indirectly proofed the phrases “a direct functional and structural connection between living bone and the surface of a load carrying implant.”

Keynote design is now a very popular and useful for dentists to present clinical cases to the audiences, for lecturing or even for the patients to have a perfect treatment plan in digital era. Including the well-known dental group DSD (Digital Smile Design), more and more reviews and experience have shown the benefits and convenient using simple presentation software (e.g. Keynote from Apple, PowerPoint from Microsoft and etc.) could be able to detect the possibilities of the treatment outcomes, communicate better not

only with the patients, but also with the dental technicians to have the best results in all processes.

Choosing the framework, or say, the template could affect the symmetry of this presentation. Before 4:3 size of the screen was the only choice, due to the projectors and the monitors that time. Now, we are able to design, and control the size. The following is going to suggest the ideal ratio for each kind of project.

4:3 Aspect Ratio - the traditional, the original

As the same size of our photos, it is easy to use, and simple for the presentation. Most of the projectors are able to present with terrific colors and portions. Disadvantage will be the lack of space for wide-size photos like panoramic radiographs, and the design is boring due to the limited site.

16:9 Aspect Ratio - the era of panoramic view

There is one saying that the artist Vincent van Gogh opened the gate to the panoramic view, with his fantastic “widescreen” painting such as his last artwork Wheatfield with Crows. The aspects included the scene of landscape, extending the eyesights. In dentistry, the pictures and the words could be appropriated situated in a harmony size. Panoramic radiograph or a decision tree (horizontal) could be easily placed to have the accurate proportion. It is now available in kinds of television programs (standard broadcast format in Europe digital channels), computer

templates and etc., considering the most optimal option for the presentation nowadays.

16:10 Aspect Ratio - close to the golden ratio

The most existing place of 16:10 ratio screen would be the computer displays, tablet and etc. A slice of larger than 16:9, but with more space to process. The ratio is close to the golden ratio which is approximately 1.618. It is a choice for photography portfolio.

24:10 Aspect Ratio - It is like watching a movie

24:10 ratio screen, is also called CinemaScope, which had been used in film making in the 60’s. Like the movie we saw today, the screen is wide, and useful for the information which contains a timeline, or a chart with long term results . (from left to right or etc.) It is also an excellent choice for showing the smile design, or one arch of anterior teeth to the audience, which is better than 16:9 ratio with wider space. Although the ratio is powerful for the esthetic purpose, it is not common since this kind of presentation should project in a conference hall with the exact size of screen and projector to have the perfect presenting. Using the normal ratio type of hardware will cause the presentation looks very small and difficult to read.

Since there are varieties of choices for the slides design, the main key would still be what would you do to construct your own story, and what is the message you want to share to the audiences. Like Steve Jobs said, “Pictures speak louder than words.”

Introduction

Since the risen of healthcare and oral education, people have started to seek the dental treatments that are “non-visible.” Unlike placing a prosthesis or having tooth whitening, periodontal surgery is considered as a type of therapy designed to preserve and regenerate the hard tissue and the soft tissue. Esthetics point of view would be covering the exposure of the teeth, and establishing the outcomes of the harmony between the teeth and the gingiva. In the other hand, correction of the morphologic defects is an another goal to achieve the functional purpose for further following dental treatment.1 However, without a standard protocols, the success of the the procedures is doubted. Mostly, periodontal therapies should start from the basis, which is the nonsurgical treatment - scaling and root planning (Sc/Rp) therapy.

Importance of Scaling & Root Planning One of the most essential etiological factor causing gingivitis and periodontitis would be the presence of microbiological bacteria causing plaques and calculus. Accumulation of plaque leads to gingival inflammation and pocket deepening, which in turn increases the area of plaque accumulation.1 Therapies should be processed to in able to control the circulation of the causing factors. (Figure 1)

Scaling is the removal of plaque, calculus, and stain from the crown and root surfaces. This is as opposed to root planing, which is the definitive removal of cementum or dentin from the root surface in an attempt to smooth rough surfaces and dislodge calculus.2

The purpose of scaling especially amongst patients afflicted with periodontal disease typically targets the area below the gum line. This procedure removes calculus and plaque that attach to the teeth. In situations where the periodontal disease is more severe, root planing and curettage are more often used. Typically in situations where the periodontal pocket is greater than 5mm.3

(The presence of proximal attachment loss of ≥ 5 mm in ≥ 30% of teeth.)

For the reason that plaque is more likely to stick to rough surfaces, the root surface is made smooth to eliminate plaque and calculus.this procedure is called root planing. If a patient have several deep periodontal pockets and with resorption of the gingival tissues which creates pockets that eventually lead up to erosion of the alveolar bones. Therefore, curettage or flap technique is needed to remove granulation tissues and epithelium lining to allow better adhesion between the connective tissues around the teeth.

Clinical Review

During the regenerative periodontal surgery, especially in tissue harvesting, it is important to ensure the recipient site is uninfected and able to receive bone materials and the soft tissue graft. Before the first incision, the deepness of periodontal pocket should be detected using the periodontal probe. Probing should perform at all orientation of teeth including buccal, lingual, palatal and the other interproximal aspects.

Afterwards, using the scalpel to trace along the apical region of the teeth in order cutting away the connective tissue. Apply the periosteal elevator to separate the tissue from the bony ridges of the teeth in order to create a flap-like opening. The granulated tissue and soft bony tissue are advised to remove with the ultrasonic scaler and curette, which allows the reveal of the new crestal bone to provide the nutrient to the tissue grafting.

Bone grafting material is applied within the eroded pockets and the collagen if deemed

necessary for proper recovery of the gingival tissues. Connective tissue graft from the diner site covers the bone materials to prevent the resorption of the bony tissue.

In final, the suturing is applied to uphold the flap in the adequate position. Tension release is proceeded to prevent any relapse during the wound healing stage. Periodontal dressing (COE PAK) is put to cover the wound from food, saliva and any contamination.

Conclusion

The inflammatory components of plaque in both gingivitis and periodontitis can be managed effectively for the majority of patients with a plaque control program and the non-surgical coupled with continued periodontal maintenance procedures.4 Importance of dental scaling and root planning should be applied to all the patients with similar symptoms and needs. The last, but the most essential, oral hygiene care should be monitored in able to have the best treatment outcomes for the patients and the clinicians.

As a dental assistant for more or less 3 years, it really was a very unforgettable working experience. Not unti l training for the techniques and applications did I know how precise and expensive the dental instruments are. In Taiwan, oral hygienists and dental assistants are not certificated to do oral scaling or any intra-oral treatment. However, it is very important and rigorous to educate the patients of tooth brushing, dental flossing and routine visit to the dental clinic.

As a matter of fact, people may wondering what they need to scale the teeth if they already brush them daily. According to NHI *, the ministry suggests to have the oral checkup with tooth scaling every 6 months and to ensure the oral hygiene care (visibility of caries, pain swelling, oral cancer diagnosis) of the patients and prevent the causes of periodontitis by subgingival tooth scaling. Thanks to these recall system, lots of Taiwanese are able to find their problems and treat their disease as soon as possible. (a group amount of Taiwanese citizens suffer in oral cancer due to the abuse of smoking and chewing betel nuts.)

Not only we (dental assistants) should learn from the basis of dental materials and manipulation, we also need to know the dental instruments clearly, especially with lots of equipments within a treatment. For example, dental implant surgery.

Nowadays, more and more dentists do dental implants in their private clinic. Nevertheless, there is still no such a course or a program to train dental assistants how to manage and

support during each phases of the treatment. That is why the dentists really should communicate with us and give us the clear order. To me, every surgery I have to assist is a big challenge with pressure, but I eager to do my best. Starting from taking the CT scan, how to adjust the correct position, make the appointment for the surgery, explain to the patients every stage before and after the treatment, ensure the isolation of the operating room, i ns t rumen ts and b iomate r ia l s sterilisation, manipulating dental impression,

The single interrupted sling suturing technique is the technique of choice when the goal of therapy is to reposition one of the surgical flaps at a particular occlusal apical level that is independent of the other gingival tissue height.¹

As an anchor type suture, the surgical flaps could be elevated, and positioned by the support of the adjacent tooth or implant.(e.g. healing abutment) The clinicians should notice the collapse of the soft tissue due to the incision procedures. (post-treatment) Tension release is indicated in this suturing to approach the final position of the gingiva contour that the clinicians expect.

The suturing material should be chosen according to its tensile strength and properties of the thread. Absorbable thread (e.g. Vicryl) is not advised for this kind of suturing technique due to the lost of tensile strength by time, effecting the support of the elevation. Braided (poly-filament) types of suturing generally have greater tensile strength, however, the oral hygiene should be monitored carefully because of the capillary effect of the suturing material.

The sling suture is widely used for root coverage, gingiva esthetics, open flap implant surgery and etc. The suture could be applied both buccal/ lingual side.

Practical Session

Models and animal cadavers with teeth are advised for the suturing practice. Focusing on the dissecting of the flap and the pathway of

the thread and following step-by step guideline in the following figures:

Easter vacation normally starts in April. It is always a perfect time to take a break to recharge and refresh from the studying.

Germany is a lovely choice, where you could discover both high technology and there traditional culture at the same time. I have managed some places to visit during these holidays. Heidelberg, Black Forest and Mainz.

Heidelberg

Heidelberg is a beautiful town beside the Neckar River in southwestern Germany, its beauty and timelessness inspired the German Romantic Movement, and it continues to inspire people today. Known for its university and castle, Heidelberg celebrates both the old and the new, making it the perfect place for everyone. Visitors can ride the Bergbahn funicular to reach the castle and its gardens, which have sweeping views over the river and the baroque Altstadt (Old Town).

There is a cool statue which is just right in front of my hotel is designed by Heidelberger Druckmaschinen which is a German precision mechanical engineering company with head offices in Heidelberg. (Figure 2)

One of the delightful visit would be the Heidelberg Castle, a famous ruin in Germany and landmark of Heidelberg. The castle ruins are among the most important Renaissance structures north of the Alps. Since it is situated on the hill, you can reach the castle by walking

and taking funicular. And apparently I chose the easy way!

Black Forest - (Freiburg, Gengenbach)

Next destination, Freiburg, where sits on the edge of the Black Forest. I would say this is the best part of my trip.

Since it's foundation in 1120, Freiburg in Germany has become a cultural and historical mosaic of colours and variety. Situated in the heart of the Black Forest in the South Western tip of Germany, Freiburg is the home to those who thrive cultural diversity and high quality education, not to mention a tourist magnet for those who love a perfect European vacation.

According to this massively large forest, renting a car would be advisable in Freiburg, and the what would match the lifestyle of German? Mercedes-Benz of course! (Figure 3)

Another amazingly lovely town would be Gengenbach, a town in the district of Ortenau, Baden-Württemberg, Germany and a popular tourist destination on the western edge of the Black Forest with about 11,000 inhabitants.

Cobble stone streets were edged with mountain water was flowing freely toward the river all around Gengenbach, which is like a beautiful puzzle you could decorate in your home.

Without any specific plan, you could drive around the Black Forest (Figure 4) to find somewhere away from the tourist attractions; and according to that, there are no English descriptions among these towns so just enjoy the beautiful views!

Mainz

Mainz, is famous for its university, its Roman heritage, its status as a media hub and regional capital, and its three most defining features: the Romanesque cathedral, the Gutenberg printing press and the Rhineland carnival. The people of Mainz have good reason to be proud of their city's history spanning almost 2,000 years. This rich cultural heritage incorporates a well-established wine growing tradition, which only adds to Mainz's appeal.

I've always enjoyed traveling and having experience with different cultures and different people and it's also a wonderful thing to be able to benefit and enable to relax my mind, not only in our country but around the world.

Focus on the journey, not the destination. Joy is found not in finishing an activity but in doing it.Black Forest is one of my favourite place to travel, and also it’s the top recommendation I would tell my friends to go!
