Brief Summary

Alveolar ridge expansion is suggested for alveolar crest thicknesses of 3-5 mm. Osseodensification (OD) and screw expansion (SE) techniques have been utilized to expand narrow alveolar ridges (NAR). This study aims to compare the implant stability quotient (ISQ) values of endosteal dental implants (DIs) inserted into NAR via osseodensification versus manual screw expansion.

Detailed Description

This study aimed to evaluate implant primary stability using Densah bur in comparison with screw expander in narrow alveolar ridge.

The patient is instructed to gargle with 0.2% chlorhexidine mouthwash, scrubbing the perioral area with 10% povidone iodine and draping the patient head with disposable drapes.

The surgery will be performed under local anesthesia using lidocaine hydrochloride 2% with adrenaline 1:8000, the surgical procedure started with flap reflection. A mucoperiosteal elevator was used to reflect the buccal and palatal flaps that were enough to expose the crestal part of alveolar ridge with clear visibility and accessibility.

For Expander group:

The screw expanders will be use to expand the osteotomy site. The diameters will be use 2.3mm ,2.6 mm, 3 mm, 3.4 mm, 3.8 mm in a successive manner. Each expander will be screw until 10 mm of depth is reached as mark on the expander. Each expanders is gently screwed half turn at a time; to allow slow and gradual expansion of the bone . When necessary, the kit ratchet is used to reach the full depth required. After the use of the final expander, an implant of appropriate size will place.

FOR DENSAH BUR GROUP :

The Implant motor is set in an anti-clockwise direction and drilling speed is set at 1000 rpm. Densah Burs will use in increasing diameters of 2mm,2.3mm,2.5 mm, 3.0 mm,3.3mm, and 3.5 mm in asuccessive manner and under copious irrigation with sterile saline.

When the haptic feedback of the bur is encountered, pressure is modulated by a pumping motion in and out of the osteotomy until 10mm of depth is reached as mark on the bur . After the use of the final expander, an implant of appropriate size will place.

For both groups After implant placement, the integrity of the buccal bone will examine for any cracks. The Smart peg\* corresponding with the implant system is placed on the implant and Osstell device is use to measure ISQ from buccal, lingual, mesial, and distal directions. For each side, three reading were taken and an average was calculated. A healing collar will place on the implant, then the flap will approximate and suture around healing collar.

Patients is instruct to take an antibiotic after surgery every 24 hours for a week and to start non-steriodal anti-inflammatory drug every 8 hours for 2-3 days; to control the possible post operative pain and edema. Antiseptic mouthwash is also continue 3 times daily for 14 days. The patients will informe with the next appointment date so that the sutures are to be removed after 1 week.

Arm && Interventions

Group	Intervention	Description
Screw expansion group	Screw expander	threadform screw expanders with special condensing burs for lateralization and compaction of bone while simultaneously placing dental implants
Osseodensification group	Osseodensification drills	special drills to expand narrow alveolar ridges.These drills share similar advantages with osteotomes in terms of greater tactile sensitivity, faster speed, and low heat generation, all of which help to maintain healthy bone and enhance implant osseointegration.

Primary Outcome Measures

Name	Time	Method
Primary stability	At the time of surgery	After implant insertion, the multipeg was screwed into the implant fixture, and stability measurement was conducted with the Osstell® ISQ device in two directions (buccolingual and mesiodistal). The mean of these two measurements was recorded as an ISQ value.
Alveolar ridge thickness	At the time of surgery	Alveolar bone thickness was measured after osteotomy site preparation.

Secondary Outcome Measures

Name	Time	Method
secondary stability	6 months	After implant insertion, the multipeg was screwed into the implant fixture, and stability measurement was conducted with the Osstell® ISQ device in two directions (buccolingual and mesiodistal). The mean of these two measurements was recorded as an ISQ value.
