NCT06207578

Brief Summary

However, recently, most described techniques for posterior atrophic maxillary rehabilitation, are targeting more conservative, cost-effective and efficient methods for sinus elevation eliminating its lateral access. The aim of the present study is to evaluate and compare the long-term implant stability for implants placed by the novel crestal sinus approach versus osseodensification using Densa-bur in Atrophic Posterior Maxilla.

Outcome Measures

Primary Outcomes (1)

  • Long- term Implant Stability

    Resonance frequency analysis will be employed with a dedicated device (Osstell). For each implant, implant stability quotient ISQ values will measured from the four sites (mesial, distal, buccal, and palatal sites). The mean of all measurements will be rounded to a whole number and regarded as the final ISQ of the implant. ISQ values will obtained after implant placement (T1), after loading (T2), 6 months after loading (T3) follow up intervals.

    12 months

Secondary Outcomes (3)

  • Implant survivability

    12 months

  • Vertical bone height formed

    12 months

  • Post operative pain

    10 days

Study Arms (2)

Implant placement using crestal sinus approach

EXPERIMENTAL

Drilling will be done gently till reaching 0-1mm from the sinus floor, then implant placement will take place and the implant itself will be used to gently elevate the sinus up to 3-5mm.

Procedure: implant placement using crestal sinus approach

Implant placement using osseodensification

ACTIVE COMPARATOR

Using Densah bur kit foe osteotomy preparation followed by implant placement

Procedure: Implant placement using osseodensification

Interventions

a Full thickness flap will be elevated at the edentulous site with two vertical releasing incision. After flap reflection, the preparation of osteotomy will be prepared following standard implant system protocol preparation of the osteotomy. Drilling will be done gently till reaching 0-1mm from the sinus floor, then implant placement will take place and the implant itself will be used to gently elevate the sinus up to 3-5mm

Implant placement using crestal sinus approach

The implant motor will be adjusted on reverse mode with 800 to 1200 rpm. According to the desired implant dimension, Densah bur diameter will be used and then implant placement.

Implant placement using osseodensification
