This study aims to compare the implant stability values following implant placement via Osteotomes and via Osseodensification using Densah Burs versus implant placement using conventional drilling technique in patients with upper posterior partially edentulous ridges as well as evaluating the crestal bone loss around temporary restorations following the three compared drilling techniques.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Conventional drilling for implant placement | Active Comparator | Implant placement in this group will be by conventional drilling according to the manufacturer's instructions (consequent drills according to the kit provided) |
|
| Implant placement using Densah Burs | Experimental | Densah Burs provided by Versah will be used as the Osseodensification drilling technique for implant placement in this group. (consequent drilling according to the kit provided) |
|
| Implant placement using Osteotomes | Experimental | Osteotomes with different serial diameters will be used following the pilot drill to expand and condense the osteotomy site as a technique for implant placement. |

| Densah Burs | Other | Series of drilling burs inserted in the osteotomy with special design that have a large negative rake angle flute, a cutting chisel edge and a tapered shank, so as they enter deeper into the osteotomy and they have a progressively increasing diameter that controls the expansion process. These burs are used with a standard surgical engine and can densify bone by rotating in the noncutting direction (counterclockwise at 800-1,200 rotations per minute) or drill bone by rotating in the cutting direction (clockwise at 800-1,200 rotations per minute) with an in and out movement together with copious saline irrigation and increasing bone plasticity and ability to expand under rate dependent stress. |
| Measure | Description | Time Frame |
|---|---|---|
| Implant stability. | ISQ units. (Implant Stability Quotient) | Will take place at same day,1,2,3,4,6,8 ,12and 16 weeks postoperatively. |
| Measure | Description | Time Frame |
|---|---|---|
| Crestal bone loss | Millimeters in standardized periapical radiograph | Will be evaluated to determine the initial crestal bone level at day of the surgery as well at 12 and 48 weeks postoperatively. |
| Measure | Description | Time Frame |
|---|---|---|
| Patient's pain | Visual Analogue Scale (VAS) on a scale of 0 to 10 where (0) is no pain and (10) is the maximum pain. | Same day of surgery as well as 1 week postoperatively. |
| Patient satisfaction | Questionnaire (3 yes or no questions) |

| Osteotomes | Other | The osteotomes kit are a series of tools that first designed by Summers in 1994. The concept was to maintain the existing bone by compressing trabecular bone laterally and apically with minimal trauma to improve the bone density. The condensed bone in this way will have to put in act a double repairing mechanism, from one side represented by the normal processes of osteointegration and on the other side from the processes of the reparation post fracture like that depends on BMU (bone modelling units) which create new spaces for the new vessels and afterwards filling all the gaps between the bone and the implant. |
|
| Conventional drilling | Other | The implant drilling kit provided by the manufacturer will be used for the implant placement, using the pilot drill followed by consequent drills according to the size of the osteotomy needed. |
|
| Same day f surgery as well as 1 and 2 weeks postoperatively. |
| Time spent in surgery | Minutes using stopwatch. | Same day of surgery (intraoperatively) |
| Patient's pain | Number of analgesic tablets. | Same day of surgery as well as 1 week postoperatively. |
