TUM YONLERİYLE TEKDİŞ İMPLANT PLANLAMASI VE UYGULAMALARI

Günümüz dişhekimliğinin hedefi hastalara temporomandibular eklem ve çiğneme kasları ile uyum içinde olan tedavi seçenekleri sunmaktır. Dişler, çiğneme kasları ve temporomandibular eklemni birbirleriyle yakından ilişkileri vardır ve bir uyum içerisinde fonksiyon gösterirler. Eksik dişlerin tedavisinde uygulanabilecek seçenekler sabit protezler, resin bonding ile kullanılan yer tutucular ve dental implant uygulamalarıdır. Günümüzde dental implant uygulamaları %90'lara varan 10 yıllık başarı oranlarıyla erişkin hastalarda özellikle tek diş eksikliklerinde en sık tercih edilen tedavi seçeneği olmuştur. Bu derlemede tek diş implant uygulamaları ile ilgili bilgiler verilip bazı vakalar sunulacaktır

LARGE ODONTOGENIC CYSTIC LESIONS WITH ECTOPIC IMPACTED TEETH CASE REPORT

Aim: Cystic and cystlike lesions of the maxilla and mandible are primarily ellipsoid, radiolucent, and clearly demarcated and may be odontogenic or nonodontogenic. Odontogenic cysts and tumors develop during or after the formation of teeth. Most odontogenic lesions are benign, but some may exhibit aggressive and destruc- tive behavior locally. In this case report will be presented some cases like dentigerous cysts, keratocysts and an unicystic amelo- blastoma with ectopic impacted teeth and their wide variety treat- ment options from minimal invasive to more aggresive. Cases: We describe six cases, who refferred to our Oral and Max- illofacial Surgery clinic of Istanbul Universtiy Faculty of Dentistry between years 2009 and 2010 with some complaints like facial asymmetry and absence of teeth. The patient age ranged from 18 to 34 years, with sex distribution of one female and five males. According to radiological examinations large cystic lesions and ectopic impacted teeth were diagnosed. Four dentigerous cysts, one keratocyst and one unicystic amelo- blastoma were diagnosed after histological examination. Five of these lesions were located in mandibular ramus region, one were located in maxillary tuber area. Three years follow up after sur- gery was made and postoperative healing were satisfactory. Conclusions: It is important by selecting the treatment protocol. It is often difficult to distinguish cystic-appearing lesions from one another with radiography. Careful consideration of the patient his-Aim: Cystic and cystlike lesions of the maxilla and mandible are primarily ellipsoid, radiolucent, and clearly demarcated and may be odontogenic or nonodontogenic.

Piezosurgery and classical surgical techniques in surgical extraction of third molar teeth

Background:Producing a safer and less aggressive osteotomy technique, to decrease the complications in oral and maxillofacial surgery, was the main goal for the clinicians for many years. As a result of these researches piezoelectric surgery is introduced a new osteotomy technique that can support conventional osteotomy techniques in oral and maxillofacial surgery. Objective:In this study we compared piezosurgery and classical surgery techniques for mandibular third molar surgery in terms of preoperative, intraoperative and postoperative (anxiety, pain, and nerve damage and also gender and position of tooth) parameters. Methods:21 patients (14 female, 7 male) with bilateral same positioned mandibular third molars which were concluded to extract with the indications of prosthetic, orthodontic reasons and pressure pain were included in our study. All the procedures are done by same surgeon. The data were processed statistically using the SPSS (Statistical Package for Social Sciences) for Windows 15.0. Findings and conclusionNerve and vessel protection, selective, precise, less aggressive osteotomy are some advantages of piezosurgery; but it is not seemed to be significantly more beneficial than classical osteotomy method in terms of reducing perioperative anxiety and pain. No significant difference was seen between piezoelectric and classical osteotomy techniques in terms of pain, anxiety and nerve damage

The Effects of intra-Articular Injections of Botulinum Toxin A on Experimentally Temporomandibular Joint Osteoarthritis Models

Objective: The aim of this study is to investigate the changes of temporomandibular joint (TMJ) by experimentally induced osteoarthritis (OA) and the effectiveness of botulinum toxin A (BTX-A) treatment via histopathological and biochemical methods
