ABSTRACT
INTRODUCTION: An oroantral fistula is by definition 'An abnormal communication between the oral cavity and the maxillary sinus.' AIM OF THE STUDY: The aim of this study is to describe the acute and chronic OAFs and to evaluate the efficiency of the modified palatal flaps with tissue bridge in the closure of both acute and chronic OAFs of small to medium size. METHODOLOGY: The study sample was derived from a population of patients from January 2013 to 2018 with the complaint of pain and discharge through the socket. RESULT: The results of this series support the view that the use of modified palatal flap with tissue bridge is a reliable flap for the repair of both acute and chronic oroantral fistulae. CONCLUSION: The ease of mobilization, superior blood supply and minimal donor site morbidity make it an ideal flap and a reliable alternative when other techniques fail.
ABSTRACT
INTRODUCTION: Alveolar bone resorption is a significant clinical problem. Bone loss in third molar region following extraction or surgical removal not only leads to periodontal problems in second molar region but also it may lead to some serious problems like increased incidence of angle fractures. In order to reduce the risks following third molar surgery, the socket should be augmented with bone grafts. In recent days guided tissue regeneration is the most accepted and successful technique followed many authors and its efficacy has been proved. MATERIALS AND METHODS: Based upon our clinical experience, the use of bio absorbable collagen wound dressing such as CollaPlugTN has achieved quick healing and more primary wound coverage. Amongst the graft materials collagen is preferable due to its high biocompatibility and hemostatic ability. This study was done to assess the regeneration of bone in the extracted third molar sockets using xenograft (CollaPlugTN-Zimmer) which was compared with the normal healing on the contra lateral side. The assessment was done to analyze post-operative healing complications and to compare the bone density formed between control site and implant site radiologically. CONCLUSION: On this basis of this study, the use of collaplugTN appears to be beneficial to the patient in postoperative wound healing and also for better bone formation. The use of this material was advantageous because of its simplicity of application cost effectiveness and availability. There is enhanced wound healing and early bone formation.
