Clinicians have long expressed concern about the accuracy of the Gothic arch tracing for recording centric relation in edentulous patients. With the use of dental implants to assist in retaining complete dentures, the problem of inaccurate recordings, made for patients without natural teeth, can be significantly reduced. This article presents a technique that uses healing abutments to stabilize the record bases so that an accurate Gothic arch tracing can be made.

“…The reason for following intraoral gothic arch tracing over other method has proven to provide more accurate recording. In the study by Jones PM[ 1 ] EL-Aramany et al ,[ 5 ] Smith[ 12 ] Langer and Michman[ 13 ] Myer et al ,[ 14 ] Linsen et al [ 15 ] and Sabarigirinathan et al [ 16 ] stated that intraoral gothic arch tracing was the most precise (repeatable) method compared to other centric jaw relation methods. The use of an intraoral tracing device with central bearing point improves the accuracy and the reliability of the recording of centric relation in any complete denture technique.…”

Aim: The purpose of the study is to evaluate and compare the horizontal mandibular positions recorded between intraoral conventional tracer and intraoral digital tracer in upright and supine position. Materials and Methods: Twenty-four edentulous patients with well-formed ridge and adequate interarch distance space were selected. MATLAB software was assimilated with intraoral digital tracer and was utilized in the study for recording the horizontal movements of the mandible, i.e., gothic arch tracing by intraoral digital tracer and was observed on a laptop with the help of MATLAB Software. For each subject, multiple mandibular readings were recorded and analyzed through software, and similar readings were recorded with conventional intraoral tracers. The comparison between intraoral conventional tracer and intraoral digital tracer was done to assess the reliability. Moreover, the consistency of recording horizontal mandibular position was also compared between upright and supine position. Results: The data were procured and utilized in comparison for different positions revealed statistically significant difference by using Student's Paired t -test. The test resulted in supine position better compared to upright position ( P = 0.0001). The association between supine position with upright position was calculated using Fischer's exact test, and it was also found to be statistically significant ( P = 0.002). The Pearson's Correlation analysis was performed to check the agreement between upright and supine position and very weak downhill correlation ( r 2 = −0.130) was observed between the two variables. Conclusion: On evaluation and comparison of horizontal mandibular position, it was found that the intraoral digital tracing technique is more valid compared to conventional intraoral tracer technique. It was also observed that the consistency of reproducibility in recording horizontal mandibular position in supine position is significantly higher than upright position.

“…The Gothic arch apex stands for the retruded contact position, which is a static relative position of the jaw. Previously the Gothic arch apex was considered as the centric relation (17–20) but now the definition of centric relation has been changed (21). It has been suggested that the centric relation of the condyle may correspond to the intercuspal position of the teeth.…”

The object of this study was to determine the best inclination of the intra-oral tracing device to get optimum condylar position with the registration of tapping movement. Three appliances with different tracing plate inclinations were used in five healthy subjects. The tracing plates were set at 0 degrees to occlusal plane (horizontal); at the angle formed by drawing a line from condylar point to the stylus position at occlusal plane (inclined); then at the angle half to inclined (half-inclined). Subjects made Gothic arch and tapping movements (n = 30) at a 30 mm interincisal distance with the head Camper plane horizontal. The incisal and condylar points were tracked with a 6-degree-of-freedom jaw movement tracking system. The location of gothic arch apex, the distribution and mean position of 30 tapping points from intercuspal position were analyzed in incisal and condylar point between the appliances. Data were analyzed with repeated measures one-way anova. Results showed that mean position of tapping points were significantly different among the appliances. Half-inclined appliance recorded tapping points in a convergent area nearer to intercuspal position (IP) than other appliances. In all appliances, the contact points of the tapping movement were anterior to Gothic arch apex.
