EVALUATION OF SUCCESS OF SINGLE DRILLING IMPLANT SYSTEM (CLINICAL AND RADIOGRAPHIC STUDY)

Abstract

Introduction: Preparation of the implant osteotomy has been classically performed using drills of various shapes to conform the site to the implant's geometry. Drilling procedures may cause not only mechanical trauma to the bone but also heat-induced bone necrosis, thus representing a significant risk for failed osseointegration. As an alternative single drilling osteotomy is a technique that allows effective bone cutting with minimally traumatic procedures and less heat generation. Objectives: Evaluation of single drilling implant site preparation in affecting implant stability and crestal bone loss that takes place around the implant. Material and Methods: The study was conducted on thirteen patients having missing posterior mandibular teeth indicated for implant restoration. All implants were placed using single drilling osteotomy. After 3 months, final crowns were delivered. All implants were followed for 6 months. Clinically, each patient was evaluated for pain, swelling and stability of the implant. Radiographically, cone beam computed tomography (CBCT) was used for the assessment of marginal bone level and bone density. Results: There was a significant increase in bone density from immediate postoperative to the end of the 6 months. The mean of marginal bone level from immediately post-operative to the 3rd month was significant and from immediate to 6th month was significant. One case displayed swelling in the first week and the implant was removed (failure case) due to lack of oral hygiene maintenance by the patient. Conclusions: Single drilling osteotomy was a successful treatment procedure, with satisfactory clinical outcomes, and a low incidence of complications.
