Computer Guided Versus Conventional Surgical Removal of Deeply Impacted Mandibular Third Molar With Preservation of External Oblique Ridge

Not Applicable

• Conditions: Impacted Third Molar Tooth
• Interventions: Procedure: Conventional surgery; Procedure: computer guided surgical; Device: CBCT

• Registration Number: NCT03447067
• Lead Sponsor: Alaadden Mahmoud Abu Al Enein

Brief Summary

in patent have deeply impacted lower third molar ,dose computer guided enhance surgical outcome versus conventional surgical remove of wisdom teeth

Detailed Description

P- Patient with deeply impacted mandibular molar I- Computer guided surgical cutting stent C- Conventional extraction O- Clinical outcome sound radiographic outcomes primary outcome

- pain : each patient well be asked to rate current and worst pain intensity on visual analogue scale (VAS ) of 0-10 with Zero being no pain and Ten corresponds to the worst pain.

Secondary outcome

* evaluation of maximum inter incisal opening: assessment of MMO will be performed by measuring the distance in mm between the incisal edges of the upper and lower central incisor by using tape graduated method.

* evaluation of edema throw use nylon thread.

Arm && Interventions

Group	Intervention	Description
computer guided surgery	Conventional surgery	comprised 9 patient undergoing surgical removal of deeply impacted mandibular third molar using computer guided surgical cutting stent. Based on (panorama , CBCT and fabricating computer guided stent technique: 1- flap design 2- accurate setting stent in a predesign site 3- bony window removing according to the stent design 4- surgical separation of the teeth with extraction the remaning part . 5- identify the nerve 6- replace the bony window in to original place with stability 7- closure and depridment
