Not Applicable
Conditions
Apertognathia
Registration Number
NCT03277443
Lead Sponsor
Ammar Ribhi Abu shama
Brief Summary

In patient with skeletal open bite, Dose computer-aided surgery enhances the clinical outcomes and accuracy versus conventional model surgery

Detailed Description

P Adult Patients with skeletal open bite.

I Computer guided surgery.

C Conventional articulating model surgery

O Outcome measure:

Outcome Name Measuring Device Measuring Unit (mm)

O1 Accuracy

Computer guided: Super-imposition of virtual surgery over the post- operative CT Scan composite models ( millimeter mm)

Conventional : Super-imposition of scanned articulator with mounted casts in the pre-planned mock surgery over post-operative scanned mounted occlusion ( millimeter mm)

O2 Anterior open Bite Closure

Standardized Multi Scan CT (millimeter mm)

Recruitment & Eligibility

Status
UNKNOWN
Sex
All
Target Recruitment
14
Inclusion Criteria
  • Patients suffering from skeletal open bite caused by vertical posterior maxillary excess and/or short mandible ramus.
  • Patients should be free from any systemic disease that may affect normal healing, and predictable outcome.
  • Required two jaws orthographic surgery
Exclusion Criteria
  • Patients with any systemic disease that may affect normal healing
  • Intra-bony lesions or infections that may retard the osteotomy healing.
  • Patient with bad oral hygiene.
  • Uncontrolled Diabetes mellitus.

Study & Design

Study Type
INTERVENTIONAL
Study Design
SINGLE_GROUP
Primary Outcome Measures
NameTimeMethod
Accuracy of movement of surgical segments in millimeterup to 4 months

Computer guided Super-imposition of virtual surgery over the post- operative CT Scan composite models (millimeter mm).

Conventional Super-imposition of scanned articulator with mounted casts in the pre-planned mock surgery over post-operative scanned mounted occlusion- accuracy would be compared by difference between Intervention and control in (millimeter mm).

Secondary Outcome Measures
NameTimeMethod
Anterior open Bite Closure (positive overbite in millimeter)up to 4 months

Standardized pre-surgery movement in amount of anterior open bite closure (mm) will be determined clinically and by radiograph.
