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

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

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 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.

Inclusion Criteria:

• 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

• Healed bony sites with sufficient dimension for implant placement

  • Vertical height (≥ 10 mm)
  • Bucco-lingual dimension (≥ 5.5 mm)
  • Mesio-distal width (≥6.5 mm)

• Patients with periodontal health (PD < 4mm, BOP < 10%)

• Inter-arch space of 7.5 to allow implant restoration

• Good oral hygiene

• Cooperative patients who accepted the trial follow up period and sign the informed consent

Exclusion Criteria:

• 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
