“…Digital articulation, using artificial intelligence, has eliminated the need for facebow transfer and physical mounting. However, conventional and digital techniques still require the establishment of the anatomical occlusal plane for complete denture patients [ 50 , 51 ].…”

A Cephalometric Analysis Assessing the Validity of Camper’s Plane to Establishing the Occlusal Plane in Edentulous Patients

Complete denture fabrication requires multiple clinical and laboratory steps. One of the most critical clinical steps is establishing an anatomical occlusal plane based on hard and soft tissue references. The aim of this study was to determine whether age or gender affects the level of the Ala-Tragus plane to establish which reference point on the Tragus should be used when fabricating the occlusal plane in edentulous patients. Clinical photographs and lateral cephalometric radiographs with complete dentitions were taken from 58 volunteers at the DMD clinic at the University of Kentucky. Each photograph was superimposed over its corresponding cephalometric image. An analysis was conducted to establish the angle of the occlusal plane relative to the Ala-Tragus landmarks; this data was then grouped according to age and gender. The analysis shows that age and gender did not significantly affect where the Camper’s plane should be approximated for complete denture treatment. However, it was found that the most parallel line to the occlusal plane was Ala’s inferior border to the ‘Tragus’s inferior border. It should be noted that the volunteers’ skeletal classification was significantly related to a Cl III malocclusion tendency. Still, with this new information, functionality and esthetics can be more adequately addressed for patients undergoing complete denture treatment. Given our results, we suggest redefining the ‘Camper’s plane with a line extending from ‘Ala’s inferior border to the ‘Tragus’s inferior border instead of the superior border. Further consideration should be taken if the patient is a skeletal CL III malocclusion.

“…The lack of randomised clinical trials comparing facebow use in xed prosthodontics has been documented in systematic reviews. 4,5 The current body of evidence, however, does include clinical trials that assess the effects of different mounting methods on the occlusal adjustments required for removable appliances. These authors were an essential inspiration for the aim and methodology of the current work.…”

“…The virtual waxup was required to demonstrate a ~ 0.15mm intersection with its antagonist at each of its stamp cusps in an opposing fossa and each of the opposing stamp cusp in the design's fossae. The design had to show no other intersections with the antagonist(s) Figure (5). The waxup was exported for later utilization in the design of the three crowns required for the same participant molar in the three different groups.…”

“…The clinical implications of different virtual articulator mounting methods are not well known, and therefore it is clear that analysis of these methods is in order prior to becoming a daily procedure in clinical practice. According to systematic reviews assessing the effect of facebow use in prosthodontics 4,5 there is an absence of randomised clinical trials comparing facebow use in xed prosthodontics. Thus the idea for this randomised clinical trial emerged to bridge the gap in the literature with high level evidence.…”

OBJECTIVE: To measure the required clinical time and volume of occlusal adjustment when the maxillary cast in a virtual articulator is set using one of three methods: a face scan, average value alignment and digitization of a conventionally mounted articulator. MATERIALS AND METHODS: In this randomised, triple blind, crossover trial; 11 molars requiring a single crown restoration were enrolled. Three crowns were designed and milled for every participant molar. Each of the three crowns was fabricated with the participant’s casts virtually mounted utilizing a different virtual mounting method. An impression was taken of the crown in place prior to occlusal adjustment. Occlusal adjustment was then performed and timed. After the occlusal adjustment, an impression of the adjusted crown was taken. The pre-adjustment and post-adjustment impression were superimposed and volumetrically analyzed to determine the volume of occlusal adjustment performed. Kruskal-Wallis test was used to compare between the groups. RESULTS: No statistically significant difference in occlusal adjustment time or volume was found between crowns fabricated with different virtual mounting methods. CONCLUSIONS: A simplified approach in virtual articulator mounting appears to be justified in construction of single full coverage prosthesis. Added labor, time and cost of more elaborate virtual mounting methods seem to be counterproductive.

“…However, no inference could be drawn for its utility in partial denture prosthodontics as there was no study to draw an inference. 5 It was found through a questionnaire study that in general practice an alarming number of general practitioners skipped the final impression stage and used irreversible hydrocolloid impressions in stock trays as the definitive impressions for fabricating dentures. One School in the US also followed this regimen as they found fewer overextensions of the denture base, fewer post insertion visits, and similar patient satisfaction with the One Step "Abbreviated Technique".…”

Traditional methods will be rendered obsolete, if not supplemented by current techniques and evidence. This requires a clinician to continuously recognize, scrutinize and consolidate the best available scientific literature in the field. Continuous improvement in the quality of research conducted, as well as reporting the findings should be encouraged to improve upon current and future treatments. This review showcases the most prominent controversies in prosthodontics and how the current evidence answers the questions. A PubMed, Met line and google scholar search with the keywords, Evidence-based dentistry and Evidence-based Prosthodontics was done from the year 1960-2021. Meta-analysis of randomized control trials and systematic reviews related to the evidence in complete dentures, fixed partial dentures, implants and prosthodontics were considered in the inclusion criteria. Literature reviews and case reports were excluded from the search. Evidence-based practice is a new level of sophistication in the practice of dentistry. Rather than considering the cost of material or the individual preference of the operator, choosing the right technique to maximize clinical efficiency should be based on scientific evidence.
