Aim: This study aimed to evaluate implant primary stability using Densah bur in comparison with expanders in maxillary premolar area. Material and methods:This study was conducted on twenty patients. The patients were divided into two equal groups. Each patient received one implant at the edentulous site of missing first or second maxillary premolar. One group received implants after using Densah bur, while the other group received implants after using screw expander. After implant placement, Smart peg was placed on implant and Ostell was used to record ISQ. Implant stability was measured intraoperative and at weeks 2, 4, 6, and 8 for both groups. The collected results were tabulated and statistically analyzed. Results:The study results showed there was no statistically significant difference between (Expander) and (Densah bur) groups in ISQ reading except at surgery and week two where the highest mean value was found in (Expander) group, while the least mean value was found in (Densah bur) group. Conclusion:Within the limitation of this study, Densah bur enabled successful implant insertion with acceptable primary stability in the resorbed maxillary premolar area. Moreover, the Densah bur can be used in a faster manner.

Prosthetic rehabilitation of totally edentulous patients today is a common procedure that clinicians approach in their daily practice. The use of dental implants for replacing missing teeth proved to be a safe technique and the implant-prosthetic materials available give the possibility of having long-term clinical success 1,2. Many studies have recommended the mandibular implant overdenture as a reliable treatment modality for edentulous patients and, in particular, those who have persistent problems using conventional
