Basal Implant as an Alternative Treatment in Atrophic Posterior Ridge

Abstract

Need for Study and Background: Since basal implant usage is on a rise, this case report will show the usage of basal implants in posteriorly atrophied ridge. Basal implantology works on the concept that the jaw bone comprises of two parts one is tooth bearing alveolus or crestal part and the basal bone, the basal bone is heavily corticated and is rarely subject to infections and resorption and hence it offers excellent support to the implants as it is densely corticated and at the same time the load bearing capacity of the basal bone is many times higher than that offered by the spongy crestal bone.  A 50 years old female patient reported to the department of implantology with chief complaint of missing teeth in lower left back region of jaw since 5 years and wanted treatment for same. After taking thorough history she gave history of traumatic extraction from the same region. Past medical history was non-contributory. Aim: This case report aims at suitable rehabilitation of atrophied posterior ridge of mandible with basal implant. Methodology: The surgical procedure began by locating the drilling point for 35 and to start the drilling, the only used was 2.0 *17 mm drill at the speed of 4000 rpm under copious irrigation and was stopped when lingual perforation with the drill was felt. The implant was taken with the help of regular driver and tightened in the site prepared. At last provisional restoration was provided to check for occlusion, phonetics and esthetic implications. Since enough bone was present in fourth quadrant, conventional implant was considered in that arch and rehabilitation was done in accordance to that. Conclusion: Basal implant have various advantages over conventional implants as it decreases patient’s discomfort due to the flapless procedures which often doesn’t require sutures for flap approximation. Basal implantology cases should be meticulously planned and through knowledge of anatomical structure and bone morphology should be known to operator for its success.
