About this study
Official title: Dynamic Versus Static Jaw Relation for Implant Supported Prosthesis: Crossover Study of Chewing Efficiency
This study aims to compare the chewing efficiency of implant-supported full-arch prostheses fabricated using two different jaw relation registration techniques: conventional static jaw relation registration and dynamic jaw tracking.
Ten completely edentulous patients will be recruited from the Department of Removable Prosthodontics, Faculty of Dentistry, Mansoura University. Each participant will receive implant-supported full-arch prosthetic rehabilitation according to the All-on-6 concept. Two definitive zirconia prostheses will be fabricated for each participant, one using conventional static jaw relation records and the other using dynamic jaw tracking records, in a crossover study design.
Read more
Chewing efficiency will be evaluated using a two-color chewing gum mixing test at the time of definitive prosthesis insertion, three months after insertion, and six months after insertion. The degree of color mixing will be analyzed using dedicated image-analysis software.
The study will investigate whether dynamic jaw relation registration provides different chewing efficiency outcomes compared with the conventional static technique in patients rehabilitated with implant-supported full-arch prostheses.
Read the detailed description
Background
Conventional complete dentures are widely used to rehabilitate completely edentulous patients; however, they may not fully restore masticatory function because of limitations in retention, stability, and supporting tissue conditions. Implant-supported full-arch prostheses provide an alternative rehabilitation option that can improve prosthesis stability, oral function, and patient satisfaction.
Accurate registration of the maxillomandibular relationship is an important component of prosthodontic treatment. Conventional jaw relation registration relies on clinical records, occlusion rims, and articulator-based procedures. Digital jaw tracking systems allow recording of mandibular movements and may facilitate the development of prostheses that better reflect individual mandibular dynamics. However, the effect of dynamic jaw relation registration on chewing efficiency in patients receiving implant-supported full-arch prostheses requires further clinical investigation.
Objective
The primary objective is to compare chewing efficiency between implant-supported full-arch zirconia prostheses fabricated using conventional static jaw relation registration and those fabricated using dynamic digital jaw tracking.
Study Design
This study will use a crossover clinical design involving ten completely edentulous patients recruited from the Department of Removable Prosthodontics, Faculty of Dentistry, Mansoura University.
Participants
Eligible participants will have completely healed residual alveolar ridges, a Class I maxillomandibular relationship, sufficient restorative space, and adequate bone dimensions in the planned implant placement areas. Patients with systemic disorders affecting bone healing, contraindications to surgery, a history of head and neck radiotherapy or chemotherapy, poor neuromuscular coordination, temporomandibular joint dysfunction, or parafunctional habits will be excluded.
Interventions and Procedures
Participants will receive conventional complete dentures initially. A radiographic guide and a computer-designed surgical guide will be fabricated using a dual-scan protocol to facilitate implant planning and placement according to the All-on-6 concept in the maxilla and mandible, subject to clinical and radiographic assessment.
After implant placement and completion of the required healing and prosthetic procedures, digital implant impressions will be obtained using intraoral scanning.
Two jaw relation registration approaches will be used:
- Conventional static jaw relation registration: Maxillary and mandibular record bases and occlusion rims will be used to record the vertical dimension of occlusion and centric relation. A facebow transfer and semi-adjustable articulator will be used for mounting and articulator adjustment.
- Dynamic digital jaw relation registration: A central bearing device attached to the record bases and a digital jaw tracking system will be used to record mandibular movements and jaw relations.
Two definitive zirconia prostheses will be fabricated for each participant using the respective jaw relation registration technique. The order of assessment and prosthesis use will follow the finalized crossover protocol.
Outcome Assessment
The primary outcome will be chewing efficiency, assessed using a two-color chewing gum mixing test. Participants will chew the test material for specified numbers of chewing strokes. The flattened specimens will be analyzed using ViewGum software to quantify color mixing.
Measurements will be performed at the time of definitive prosthesis insertion (T0), three months after insertion (T3), and six months after insertion (T6), according to the finalized study protocol.
Statistical Analysis
Data will be analyzed using SPSS software, version 26. Quantitative data distribution will be assessed using the Shapiro-Wilk test. Normally distributed data will be summarized as mean and standard deviation, while non-normally distributed data will be summarized using the median and an appropriate measure of dispersion. Statistical tests appropriate for the crossover design, repeated measurements, and distribution of the data will be used. Statistical significance will be set at p ≤ 0.05.

What is being measured
The primary outcome is the main question the study is designed to answer.
Chewing Efficiency Assessed by Two-Color Chewing Gum Mixing Test
Chewing efficiency will be assessed using a two-color chewing gum mixing test. Participants will chew two differently colored chewing gums, and the resulting specimens will be flattened to a standardized thickness and analyzed using ViewGum software to quantify color mixing. Chewing efficiency will be compared between implant-supported full-arch prostheses fabricated using conventional static jaw relation registration and dynamic digital jaw tracking. The analysis will follow the prespecified scoring method, with the measurement scale and interpretation defined in the study protocol.
Measured: At definitive prosthesis insertion (T0), 3 months after insertion (T3), and 6 months after insertion (T6).

This study aims to compare the chewing efficiency of implant-supported full-arch prostheses fabricated using two different jaw relation registration techniques: conventional static jaw relation registration and dynamic jaw tracking.
Ten completely edentulous patients will be recruited from the Department of Removable Prosthodontics, Faculty of Dentistry, Mansoura University. Each participant will receive implant-supported full-arch prosthetic rehabilitation according to the All-on-6 concept. Two definitive zirconia prostheses will be fabricated for each participant, one using conventional static jaw relation records and the other using dynamic jaw tracking records, in a crossover study design.
Chewing efficiency will be evaluated using a two-color chewing gum mixing test at the time of definitive prosthesis insertion, three months after insertion, and six months after insertion. The degree of color mixing will be analyzed using dedicated image-analysis software.
The study will investigate whether dynamic jaw relation registration provides different chewing efficiency outcomes compared with the conventional static technique in patients rehabilitated with implant-supported full-arch prostheses.
