Abstract

With the advancement in science and technology, Immediate implant placement has become a widely used and well accepted alternative to traditional treatment protocols. Post extraction implant placement in multicoated molar area is challenging. The primary stability in molar areas is achieved by engaging the interradicular bone but slipping of osteotomy drill to mesial or distal root socket during implant bed preparation is the main problem in post extraction immediate implant placement. Use of surgical guide, pre- extractive interradicular implant bed preparation and the combination of both these techniques has been used to overcome the problem related to immediate implant placement at molar sites. This paper presents an alternative approach in immediate Implant placement in multi rooted molar area that uses the anatomy and morphology of roots in guiding the osteotomy to provide an ideal3-dimensional implant positioning.

Highlights

Immediate implant placement is defined as the placement of an implant into the extraction socket at the time of tooth extraction.[1]
The placement of immediate implant was reported by Schulte and Heimke and Schulte et al in 1976.2 Immediate implant placement offers many advantages over the conventional approach which includes fewer number of surgical procedures, reduction in overall treatment time, increase in patients comfort and satisfaction.[3,4]

Summary

Introduction

Immediate implant placement is defined as the placement of an implant into the extraction socket at the time of tooth extraction.[1]. Guiding pin was placed in initial osteotomy site and radiograph was taken to ensure the correct direction of the osteotomy (Fig. 4). The length of the implant was selected to extend between 2 or 3 mm beyond the apices of the tooth to be extracted to enhance the initial stability of the implant. In this case, dental implant of 4.5 x 12 mm (Bredent) was placed. After 4 months following the procedure, a radiograph was taken which showed a complete healing of the extraction socket and healthy peri implant tissue condition prosthetic treatment was initiated (Fig. 9). Zirconia screw retained crown was given as definitive restoration (Fig. 11-12)
