Isolated sinus pneumatization after single tooth extraction indicate sinus lifting for proper implant placement. The conventional way of using osteotomes to elevate the sinus is annoying to patient and also does not give the needed amount of bone around the implant. Introducing new intervention of Densah Burs helps increase bone gain around implant and decrease the patient discomfort.
The rehabilitation of the edentulous posterior maxilla using osseointegrated implants is often challenging due alveolar bone resorption, low bone density and maxillary sinus pneumatization. Maxillary sinus lift is one of the most common surgical techniques used for increasing the available bone volume to place implants and restore function and esthetics. Trans-crestal approach can be successfully adopted when residual bone height is at least 5 mm. Osteotome sinus floor elevation was first in 1994, and proved to be less invasive, more conservative, less time consuming, and reduces postoperative discomfort to the patient. Moreover, this technique was found to yield predictable results with success rates of at least 95%.
Osseodensification is a new surgical technique of biomechanical bone preparation performed for dental implant placement where bone is compacted and auto grafted into open marrow spaces and osteotomy site walls in outwardly expanding directions. It was reported that osseodensification increases the bone-implant contact, bone density, and primary stability. Moreover, the insertion torque peak is directly related to implant primary stability and host bone density. Furthermore, for every 9.8 N cm of torque increased, a reduction in failure rate of 20% in single-tooth implant restoration was observed.
The objective of this study is to evaluate crestal sinus elevation using osseodensification versus osteotomy clinically and radiographically in terms of marginal bone loss, primary and secondary stability and bone gain around the implant.

Exclusion Criteria:
Patients should not have taken drugs, especially bisphosphonates or drugs altering bone metabolism, within 2 months before the inclusion in the study.
Closed sinus lifting will be performed using densah burs and then dental implants will be placed.
Procedure: Closed sinus lift using osteotomes
Sinus lifting will be performed using osteotomes and then dental implants will be placed.
Procedure: Use of Densah Burs in closed sinus lift
Closed sinus will be performed using Densah Burs. Densah Burs enhance bone quality through osseodensification; a process through which bone is compacted and auto-graphted in the marrow spaces and apically to elevate the sinus floor and enhance bone density.
Closed sinus lift will be performed using osteotomes. Osteotomes elevate the sinus floor and enhance the bone quality.
Measurement of Bone Change in Cone Beam CT
The amount of bone change will be determined by superimposing pre-operative CBCT (cone-beam computed tomography), three months post-operative, and six months post-operative CBCT.
Time frame: three and six months
Measurement of Primary and Secondary Implant stability using Resonance Frequency Analysis (RFA)
The implant stability quotient (ISQ) of the implants will be measured using a resonance frequency analysis measuring device, that is, Ostell, at the time of placement, which is the primary stability, and after six months, which is the secondary stability. The implant stability quotient has a scale ranging from 0 to 100 in which 0 is a failed implant and 100 is maximum implant stability.
Time frame: At the day of implant placement and after six months
