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.
Patients with an age range of 25-70 years
Patients with systemic health
Patient with missing teeth in the upper posterior area
Patients with D3 or D4 type of alveolar bone
Pregnant females
Smokers
Patients with habits that may compromise the longevity and affect the result of the implant as alcoholism or parafunctional habits
History of radiotherapy or use of bisphosphonates
Parallel
Densah Burs
Other interventionSeries 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.
Osteotomes
Other interventionThe 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 interventionThe 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.
