The remnants of roots were atraumatically extracted, and the bony defects around the implant were grafted with synthetic resorbable bone substitute β‐ Tricalcium phosphate, and the flap was sutured. Three months later, implants were restored with single crown fixed prostheses. Patients were followed up at 6, 12, and 18 months after insertion using periapical standardized radiographs to monitor the changes in the marginal bone l...

The immediate placement of single postextractive implants is increasing in the everyday clinical practice. Due to insufficient bone tissue volume, proper primary stability, essential for subsequent osseointegration, is sometimes not reached. The aim of this work was to compare two different approaches: implant bed preparation before and after root extraction. Materials and Methods: Twenty-two patients of both sexes were selected who needed an implant-prosthetic rehabilitation of the fractured first mandibular molar or presented an untreatable endodontic pathology. The sites were randomly assigned to the test group (treated with implant bed preparation before molar extractions) or control group (treated with implant bed preparation after molar extractions) by a computer-generated table. All implants were placed by the same operator, who was experienced in both traditional and ultrasonic techniques. The implant stability quotient (ISQ) and the position of the implant were evaluated. Statistical analysis was carried out. Results: In the control group, three implants were placed in the central portion of the bone septum, while eight implants were placed with a tilted axis in relation to the septum; in the test group, all implants were placed in ideal positions within the root extraction sockets. The different position of the implants between the two procedures was statistically significant. Conclusion: This work presented an innovative approach for implant placement at the time of mandibular molar extraction. Preparing the implant bed with an ultrasonic device before root extraction is a simple technique and also allows greater stability to be reached in a selective case.
Root Guided Immediate Implant Placement at Mandibular Molar Site: A Case Report
Journal of Nepalese Prosthodontic Society
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.
e placement of immediate implants in the posterior sector is a widespread procedure where the success and survival rates are similar to those of traditional protocols. It has several anatomical challenges, such as the presence of interradicular bone septa that hinder a correct three-dimensional positioning of the implant and may compromise primary stability and/or cause damage of neighboring structures. e aim of this article is to present the treatment and the one-year clinical follow-up of a patient who received immediate implant placement using an interradicular bone-drilling technique before the molar extraction.

Background: Immediate implant insertion in mandibular molar extraction sockets raises a series of challenges for clinicians. Purpose: This preliminary study demonstrates the use of a modified insertion technique of implant placement at the time of mandibular molar extraction. Materials and Methods: Immediate implants were placed at the time of molar extraction in 20 patients; a sulcular buccal incision with releasing periosteal incisions were made around the mandibular molar to be replaced, and implant insertion into the interseptal/interradicular bone was performed. The remnants of roots were atraumatically extracted, and the bony defects around the implant were grafted with synthetic resorbable bone substitute β-Tricalcium phosphate, and the flap was sutured. Three months later, implants were restored with single crown fixed prostheses. Patients were followed up at 6, 12, and 18 months after insertion using periapical standardized radiographs to monitor the changes in the marginal bone level. Results: Our modified insertion techniques showed an implant survival rate of 95%; one implant failed 4 weeks after insertion. No significant marginal bone loss around the implant was recorded at all times of follow-up. Satisfactory soft issue parameters were achieved. Conclusions: The combination of immediate implant placement with engagement of the interseptal/interradicular bone, atraumatic extraction of remnant roots, and concomitant regenerative therapy showed preliminary favorable outcomes. However, wider application of this technique for longer following up periods is required for further conclusive recommendations.
Early and immediate implant placement with a root-analog implant design is a well established and proven protocol for placing dental implants. Results of more than 25 years of clinical and statistical data indicate that predictable long-term success can be achieved 1,2 . Moreover, immediate placement offers significant benefits to both the patient and the clinician. The number of surgeries is minimized and overall treatment time is shortend. Width and height of the alveolar bone is preserved, an a better implant location results in maximal function and esthetic soft tissue support.

Background: Immediate implant placement to simultaneously replace mono-radicular teeth at the time of extraction has gained wide acceptance as a reliable and predictable treatment option. Application of this option in replacement of molars has presented a difficult challenge both surgically and prosthetically. Aim of the study: The current study aimed to investigate the efficacy of wide diameter implants in the immediate replacement of mandibular molars over a period of 24 months. Methods: Thirty implants were utilized in the immediate replacement of mandibular molars in a one stage surgical procedure following the atraumatic extraction of the teeth. The implants were restored after three months and followed-up at 12 and 24 months to evaluate the crestal bone loss around them. Results: A survival rate of 96.6% was evident at the end of the study period (24 months) with a mean crestal bone loss of 0.33-mm at 12 months and 0.19-mm at 24 months with a total mean crestal bone loss of 0.52-mm during the study period. Conclusion: Wide diameter implants are a reliable and predictable means to immediately replace mandibular molars with stable long-term prognosis with the consideration of proper extraction procedures and maintenance of the socket architecture.
