“Radiographic Methods in Evaluating Marginal Bone Levels Around Dental Implants”

Abstract:

One of the most important success criteria in oral implantology is the marginal bone loss. Since it is difficult to detect small defects clinically, radiography plays an important role. Daily routine practice necessitates the use of extraoral oral or intraoral radiographies which are digitized for measurements because of their ease of operation. These measurements are performed usually at %2000 magnification. Nevertheless for scientific studies the method of choice should be digital subtractionradiography of standardized images because it is very precise. For obtaining 3 dimensional information the only possible radiographic technique is dental volumetric tomography which provides in contrast to 2 dimensional applications data about vestibular bone loss rate.

Key words: standardized radiograph, subtraction radiography, panoramic radiograph, dental volumetric tomography, marginal bone loss

“Bruksizmin Dental İmplantlar Üzerine Etkisi ve Alınabilecek Önlemler”.

“EFFECTS OF BRUXISM ON DENTAL IMPLANTS AND PREVENTIVE MEASURES”

Abstract:

Generally, bruxism is seen as an etiological factor of TMD, tooth atrision, periodontal tissue loss and damage on dental restorations. In spite of lacking proof, it is often accepted as a contraindication for the dental implant treatment due to the overload transmitted to the implant bodies and surrounding bone. Studies investigating the role of bruxism on load transfer to the implant surrounding bone, point out to the fact that a proper planning and preventive measures can be of  great importance in avoiding the destructive forces caused by bruxism and lead to long-term success similar to routine implant treatment.

Key Words: Bruxism, dental implants

Abstract:

Dental implants have been successfully used to restore completely and partially edentulous patients. In recent years, an increasing number of publications on immediate loading of dental implants have appeared in the literature and high survival rates were generally reported. But, edentulous upper jaw used less than lower jaw in publications. Therefore, recent develops in immediate implant loading of edentulous upper jaw evaluated in this collection.

"Tam Protez hastalarında kullanılan implant üstü hareketli protezlerde bar tutucular".

“Bar Attachments in Implant Overdentures”.

Abstract:

One of the possible attachment systems for overdentures are bars. The choice of the attachment system is one the most difficult tasks for the clinician. The decision depends on multiple variables such as oral hygiene, anatomic factors, biomechanical criteria, the expectations of the patient, as well as the economic situation of the patient. This article is a guide to fabrication steps of bar attachments, as well as an aid for decision making in the choice of attachment system.

As a conclusion, there is no proof that bar retainers are more advantageous, although it is well known that bar retained dentures are more stable, good for sharing the load between the supporting teeth or implants, thus allowing mandibular 4 implants to be immediately loaded. The disadvantages seem to be the high costs and the complexity of fabrication steps and the difficulty to solve a problem occuring with bar type of retainers.

“Immediate Implantation and Immediate Loading: A Review and Presentation of 2 Cases”.

Abstract:

Since the first report of the placement of a dental implant into a fresh extraction socket, there has been increasing interest in this technique for implant treatment. The advantages of immediyate implant placement have been reported to include reductions in the number of surgical interventions and in the treatment time required.

Correct indication, surgical technique and prosthetic protocol results in success for immediyate loading as well as immediyate implantation. If even one of the factors related to the patient, such as systemic condition, smoking habit, poor oral hygiene, biotype and an infection in the extraction region is negative, this treatment option should not be considered. The patient satisfaction is very high and difficulties related to the implantation site in late implantations is eliminated.

A patient with immediyate implantation and immediyate loading, another with only immediyate loading, both for the upper incisors with 4 months of follow-up are presented in this article.

“An upper full denture causing phonetic problems and the solution of the problem”.

Abstract:

As it is well known, complete dentures can cause speech or phonation problems right after insertion. The denture base is covering the whole palate and especially in patients wearing dentures for the first time this fact is considered to be quite normal. However, a complication or mistake in the fabrication of the denture can also be the reason of speech problems.

A patient who was treated by an intern student in the Department of Removable Dentures, complained of difficulties of pronouncing the consonants K and G, right after insertion of the complete upper denture. After inspection of patient and denture, a very thick denture base in the posterior part of the denture could be detected. In this case report the clinical and laboratory procedures to solve the problem were described and shown by several illustrations.

“Sigara Dumanının Diş İmplantları Üzerine Etkileri: Güncel Yaklaşım Ve Düşünceler ”.

“Cigarette smoking and osseointegration”.

Abstract:

Dental clinicians have always had a careful attitude towards patients with smoking habits. It is a well known fact that factors causing environmental air pollution and cigarette smoke can have a negative effect on the osseointegration mechanism, as in osteoporosis and in periodontal diseases. Smoking is a contraindication for implant therapy and patients should be informed that they are at a higher risk of implant failure if they are smokers. Aryl hydrocarbon receptors are found in the cytosol of mammalian cells and are important in the bone metabolism. Products in cigarette smoke being known as aryl hydrocarbon receptor ligands, such as 2,3,7,8-tetrachlorodibenzo-p-dioxin, benzo-[a]-pyrene and dimethyl-benzathracene, are thought to be bound to the receptor and inhibiting osteogenesis as well as bone formation. A recently found antifungal agent, resveratrol, acts as an antagonist and thus can reduce the negative effects of these ligands. Resveratrol seems to be, in a short term, useful for protection of implant patients or patients receiving artificial joints and having smoking habits or being subject to heavy smoke.

“Uygun İmplant Sistemini Seçmek İçin Hangi Kriterler Göz Önünde Bulundurulmalı”

“A Guideline Proposal For Decision Making In Choice Of An Implant System”.

Abstract:

The purpose of the authors in this review is to offer a guideline for clinicians, who have difficulties making a decision among numerous systems with a variety of materials, body shapes, diameters, lengths, platforms, surface properties and coatings, offered by many manufacturers. Implant systems are becoming more similar with the passing years and dentists can have difficulties making a choice of an implant system to establish in their clinics. Recent papers estimate that nearly 1,300 different implant configurations are currently available.

The criteria in this text are basing on objective scientific facts, but some criteria include subjective opinions of the authors, too.

A modern implant system should require six main properties: conical or cylindrical root form, titanium material, screw threads, a large palette of diameters, lengths and prosthetic parts and a sound scientific support. If a system is lacking at least one of those requirements, it would be better not to be drawn under consideration.

After elimination of systems not containing these criteria, the choice will be decided by subjective factors such as relations to the company salesmen or by factors such as costs or technical and inquiry support.

 “İmplantlarda Erken Krestal Kemik Rezorpsiyonu ve Oklüzyonun Önemi“.

„Early Crestal Bone Resorption of Dental Implants and the Role of the Occlusion“.

Abstract:

The clinical success and longevity of endosseous dental implants depend in large part on the health of soft tissues as well as bone tissue surrounding the crestal region. Crestal bone loss has been reported to be of greater magnitude and to occur with greater frequency during the first year, averaging 1,5 mm, and 0,1mm in average in the subsequent years. For the explanation of early crestal bone loss, five main hypotheses were declared. Several studies have shown occlusal factors to be the most important factor causing early crestal bone loss. The prosthodontist should determine the number and size of implants in consideration of dental and medical anamnesis, bone density and quantity, and also psychology and expectations of the patient. Although there is no magic key or formula for the occlusion of all implant supported dentures, it can be recommended that generally implants should be protected from horizontal forces, and contacts should evenly be distributed between all implants and if possible, also to natural teeth.

“The Evaluation of Four Different Methods in the Treatment of Candida Induced Denture Stomatitis”.

Abstract:         

Denture related stomatitis (DRS) was determined as the most frequently encountered inflammatory lesion associated with denture wearing  and affects 11-67% of denture wearers and is most often seen under full upper dentures. A change in wearing and cleaning habits is not sufficient in the treatment of Candida associated stomatitis and should be supported by antifungal drugs. In antifungal therapy four different treatment modalities are generally accepted:

0.5% sodium hypochlorite solution, 0.2% chlorhexidine gluconate solution, systemic use of azole derivates or nystatin. 60 removable denture patients with microbiological positive results were included in the study group and treated randomly in four different treatment groups for a period of two weeks. The results showed that the itraconazole-nystatin treatment group was microbiologically and clinically more effective than the other groups, although the clinical effectiveness could not be supported statistically.
