Graftless Lateral Sinus Lifting Using Peizo Electric Device in Patients With Atrophic Maxilla

Background: Dental implant therapy in the posterior maxilla may be difficult owing to limited bone height after dental extraction with sinus pneumatization. Several approaches for sinus floor elevation have been documented, and hence lateral sinus lifting using surgical guide is used.

Aim of the study: To compare between guided and conventional sinus lifting using piezoelectric device in patients with atrophic maxilla.

Methods: This study will be carried out as a randomized controlled clinical trial; patients will be randomly allocated into two groups: in the study group 15 patients will undergo lateral sinus lifting using surgical guide, while in the control group 15 patients will undergo conventional sinus lifting without surgical guide with simultaneous implant placement.

Clinical evaluation including intraoperative assessment of duration of surgery and immediate complications such as perforation of Schneiderian membrane, arterial laceration and trauma to adjacent roots and nasal bleeding. Primary implant stability will be measured immediately after implant placement

Treatment and study plan

lateral sinus lifting with guide

Procedure

Including 15 patients who will be treated by lateral sinus lifting using a surgical guide with simultaneous implant placement.

conventional lateral sinus lifting

Procedure

including 15 patients who will be treated by conventional lateral sinus lifting without using a surgical guide with simultaneous implant placement.

Primary outcomes

  1. implant stability

    Time frame: 6 months

    • Secondary implant stability will be measured 6 months post-operatively using Osstell device.

  2. change in pain scores

    Time frame: up to 7 days

    • Post operative pain will be assessed through a 10 point visual analogue scale (VAS). (0-1=none, 2-4=mild, 5-7=moderate, 8-10=severe)

  3. Post operative edema

    Time frame: 1 week

    it will be assessed in the 1st week as following:

    • None (no swelling)
    • Mild (intra oral swelling confined to surgical field)
    • Moderate (extra oral swelling in the surgical zone)
    • Severe (extra oral swelling spreading beyond the surgical zone)
