Implant Stability Changes Using Different Technique in Posterior Maxilla With Early Loading Protocol

Implant Stability Changes Using Densah Burs Versus Magnetic Mallet Technique in Posterior Maxilla With Early Loading Protocol: A Randomized Clinical Trial

60 implants were placed in patients seeking implantation of their lost posterior maxillary teeth (premolar and molars) with normal bone height beneath the floor of the maxillary sinus. The patients were selected from those attending the outpatient clinic of the Oral & Maxillofacial Surgery Department, Faculty of Dentistry, Mansoura University.

60 implants will be randomly and uniformly divided into two equal groups: Group 1: It was consisted of 20 inserted dental implants by Densah burs into healed posterior maxillary alveolar ridge with an early loading pattern.

Group 2: It was consisted of 20 inserted dental implants by Magnetic Mallet technique into healed posterior maxillary alveolar ridge with an early loading pattern.

Group 3: It was consisted of 20 inserted dental implants by Conventional Drilling technique into healed posterior maxillary alveolar ridge with an early loading pattern.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Implant stability	Implant stability was assessed at the time of implant insertion, 1 month and 2 months after surgery. The analysis of resonance frequency analysis (RFA) was made using an Osstell Mentor apparatus. The smart peg was attached to the dental implant. The RFA value was measured 4 times in 4 directions (every 90°). The results were expressed as implant stability quotient (ISQ) and averaged for each implant. The ISQ scale ranges from 0 to 100. The values less than 60 indicate low implant stability, values from 60 to 69 indicate medium stability, while values from 70 to 79 indicate high stability.	2 months
