Официальное название

Clinical and Radiographic Evaluation of Implant Stability in Healed Maxillary Posterior Sites Comparing Osteotome, Osseodensification and Conventional Drilling Implant Placement Techniques: A Randomized Clinical Trial

Обзор

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.

Подробное описание

* Patients with partially edentulous ridges seeking restoration of their missing teeth, with enough measurements for implant placement will be recruited from the outpatient clinic of the Oral Medicine and Periodontology Department, Faculty of Dentistry-Cairo University to participate in this study and will be randomized to be either undergoing conventional drilling according to the manufacturer's instructions (control group) or either one of the two intervention groups; Intervention group (A) where implant placement will be done using the Osseodensification technique by the Densah burs or Intervention group (B) where the implant placement will be done using the Osteotomes. * Neobiotech IS III active implants will be used in this study, they have an osseoconductive SLA-coated surface, a tapered design with a crestal macrothread design (0.8 pitch), a self compactable apex as well as deep thread to maximize implant stability. The implant has a platform switching feature and a conical/hex design. * A temporary PMMA crown after 3 months from implant placement and will be kept for follow up for a year then definitive final restoration will be made.

Вмешательства

• Другое Densah Burs
  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 direc
• Другое Osteotomes
  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 u
• Другое Conventional drilling
  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.

Первичные конечные точки

• Implant stability. [Срок оценки: Will take place at same day,1,2,3,4,6,8 ,12and 16 weeks postoperatively.]

Вторичные конечные точки (1)

• Crestal bone loss [Срок оценки: Will be evaluated to determine the initial crestal bone level at day of the surgery as well at 12 and 48 weeks postoperatively.]
