The aim of this study is to demonstrate the use and the effectiveness of cephalometry and golden proportions analysis of the face in planning prosthetic treatments in totally edentulous patients. In order to apply this method, latero-lateral and posterior-anterior X-rays must be performed in addition to the common procedure. Two main concerns for totally edentulous patients are the establishment of the vertical dimension and the new position of the occlusal plane. The divine proportion analysis was carried out by the use of a golden divider. The prosthetic protocol was divided into three steps and a case was selected for better understanding. Referring to the golden relations, if the distance from the chin to the wing of the nose is 1.0, the distance from the nose to eye is 0.618. This proportion is useful and effective in determining the correct prosthetic vertical dimension. The incisal margin of the lower incisor must be positioned between Point A (A) and protuberance menti (Pm) according to the gold ratio 0.618 of the total height A-Pm. Posteriorly the occlusal plane must be placed 2 mm below the divine occlusal plane (traced from the incisal margin of lower incisors to Xi point). A prosthesis made in accordance with cephalometric parameters and divine proportions of the face helps to improve the patient’s aesthetics, function and social personality.

Introduction. Optimal reconstruction of vertical dimension of occlusion is crucial for functional and physiognomic rehabilitation of edentulous patients. This article is aimed at presenting attitudes and studies on application of cephalometric analysis in obtaining optimal vertical dimension of occlusion. The review of literature presents the studies which analyse the possibilities of cephalometric analysis aimed at improving the clinical methods for vertical dimension of occlusion determination in treatment of edentulous patients. The research carried out so far can roughly be divided into: cephalometric vertical dimension of occlusion evaluation in dentulous patients performed to determine precise indicators of vertical dimension of occlusion and to establish cephalometric standards for practical application in prosthodontics; the method of producing pre-extraction cephalometric registries involves the production of cephalometric radiographs for potential prosthodontic patients in dental pre-extraction period which are kept for reference to be used in later therapy; the cephalometric method of registering the position of physiologic rest position of the mandible involves measuring cephalometric parameters in cephalometric radiographs made when the mandible is in physiologic rest position; cephalometric evaluation of vertical dimension of occlusion in complete denture therapy after clinical determination of intemaxillary relationship is recommended for timely detection of possible mistakes, with a possibility of correction in the process of complete denture production; and cephalometric analysis in edentulous patients with old complete dentures for a planned vertical dimension of occlusion extension. Conclusion. Data from the literature give no proof of a scientific and universally accepted method for precise determination of vertical dimension of occlusion, which is a point many authors agree upon. Different methods proposed for vertical dimension of occlusion determination in everyday practice are usually recommended in combination with other methods. Determination of individual, morphological vertical dimension of occlusion indicators by cephalometric analysis is, in this sense, one of the directions for finding a better solution when planning an artificial occlusion complex.

BACKGROUND: The establishment of appropriate vertical dimension of occlusion (VDO) is paramount for successful and functioning complete dentures (CDs). AIM: The aim of this study was to assess the effect of alteration of VDO on the brain activity in CD wearers. MATERIALS AND METHODS: Ten completely edentulous patients participated in this study. Each patient received three sets of CDs: one control set and two duplicates’ CDs. The control CDs was designed with appropriate VDO (control - VDO), while the duplicate CDs were designated as followed: one with VDO lowered by –3 mm (low - VDO) the other one VDO was increased by +5 mm (high - VDO). The effect of alteration of VDO on brain activity was assessed by measuring alpha waves changes using electroencephalogram (EEG) before and after chewing gum. Statistical analysis was carried out using one-way ANOVA and dependent t-test. The significance level was set at p < 0.05. RESULTS: There was a significant increase in the alpha waves mean values after chewing (p < 0.05) gum compared to before except for low - VDO CDs (p > 0.05). The control-VDO revealed a statistically significant higher mean values compared to the duplicate dentures. CDs with high - VDO showed higher mean value than low - VDO dentures, however, it was statistically insignificant (p > 0.05). CONCLUSION: Appropriate determination of VDO is not only important for the success of CDs but also for the functional augmentation of brain activity.

Abstract Introduction The aim of modern cephalometrics is to evaluate the relationship of skeletal and dental functional units of the face and to implement treatment to establish the position of the units horizontally and vertically. Establishing a correct occlusal vertical dimension is considered one of the most important aspects of facial esthetics for patients in need of orthodontic treatment. Aim The aim of this study is to evaluate the vertical dimension of occlusion in varying dental malocclusions in Solan population. Materials and Methods The sample consisted of pretreatment lateral cephalograms of 100 patients (50 Class I and 50 Class II div 1), aged 15 to 30 years; six angular and one linear parameters were measured to determine the vertical dimension of occlusion. Results All the parameters (Frankfort-mandibular plane angle [FMA], Occl/Frankfort horizontal plane [FHA], angle of Y-axis, Occl/SN, GoGn/SN, and ANS-Me) were found to be decreased in Class I than in Class II div 1 malocclusion except (ANS-Xi-Pm). All the parameters were found to be statistically significant (p < 0.05) when compared between groups. When cephalometric norms of the present study were compared with Moroccan population, all parameters (ANS-Xi-Ptm, FMA, Occl/FH, Occl/SN, GoGn/SN, and ANS-Me) were found to be decreased in Solan population except angle of Y-axis. All the parameters were clinically significant (p < 0.05) except ANS-Xi-Pm and FMA that were found to be clinically nonsignificant (p > 0.05). Conclusion Solan population has distinct cephalometric characteristics, which should be used as the reference in future orthodontic treatments.
