Mandibular Flexure in Patients
- Conditions
- Mandibular Flexure
- Interventions
- Diagnostic Test: Mandibular flexure evaluation
- Registration Number
- NCT05718050
- Lead Sponsor
- University of Rome Tor Vergata
- Brief Summary
The flexion of the mandible (MF) is a multifactorial phenomenon that occurs simultaneously with mandibular movements determining changes in the shape of the mandible. mandibular flexure (MF) may cause complications and failures in both conventional and implant-supported fixed dental prostheses (FDP) especially when a long-span prosthesis is planned to connect the anterior to the posterior region of the mandible. Previous studies reported increased biomechanical stress at the prosthetic and implant level, poor passivity of fit, impression distortion, pain during function, de-cementation of the prosthesis, porcelain chipping, prosthetic screw loosening and fracture, bone resorption and implant fracture. The aim of this study is to quantify the dimensional changes related to MF by means of a cone beam computed tomography (CBCT) between maximum opening (MO) and maximum intercuspation (OVD) positions. The null hypothesis was that there is no significant difference in terms of length and width of the mandible between maximum intercuspation and maximum opening positions.

- Primary Outcome Measures
Name Time Method Mandibular Flexure in maximum opening (MO) 24 hours A blind assessor made 4 four measurements per patient on an implant planning software (DTX Studio Implant software, Dexis LLC), evaluating the distance between the fiducial landmark at the contralateral canines and contralateral molars, and between ipsilateral canines and molars on both sides
Mandibular Flexure in Occlusal Vertical Dimension (OVD) 24 hours A blind assessor made 4 four measurements per patient on an implant planning software (DTX Studio Implant software, Dexis LLC), evaluating the distance between the fiducial landmark at the contralateral canines and contralateral molars, and between ipsilateral canines and molars on both sides
