Digital methods for recording jaw relationships in patients with tooth loss

Restorative Comparison of Facebow and Simplified Techniques for Digital Jaw Relation Records in Treatment of Occlusal Rehabilitation

NA · Hacettepe University · NCT06982898

This study is testing two different ways to record how the upper and lower jaws fit together in patients who have lost teeth to see which method works better and makes patients happier with their dental restorations.

What this trial studies

This study aims to evaluate the effectiveness of two different methods for recording the intermaxillary relationship in patients who have lost occlusal support. Participants will be divided into two groups: one will have their jaw relationship recorded using an intraoral scanner after bimanual manipulation, while the other will use a jaw motion tracking device following neuromuscular deprogramming. The study will assess the clinical success, efficiency, and patient satisfaction of the restorations produced from these methods. All procedures will adhere to standard dental preparation principles.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 65 with bilateral edentulism in the maxillary posterior region and healthy dental conditions.

Not a fit: Patients with temporomandibular joint dysfunction, orofacial pain, or those requiring removable prostheses in the mandibular arch may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy and outcomes of prosthetic treatments for patients with occlusal support loss.

How similar studies have performed: While the approach of using digital methods for jaw relation recording is gaining traction, this specific comparison of techniques is relatively novel.
