Bone height measurement of maxillary and mandibular bones in panoramic radiographs of edentulous patients

Abstract

Objectives. The purpose of this in vitro study were to determine variation in maxillary and mandibular vertical measurements and to assess vertical bone loss made from panoramic radiographs in edentulous measurements. Study Design. In this descriptive study, a total of 600 panoramic radiograph's of edentulous patient were examined. The mean ages of edentulous patients were 31 and 87 years respectively. Measurements were made from reference lines drawn from anatomic landmarks on standardized panoramic rediographs. All radiographs were made using a standardized manner by the same technician. Twelve sites were measured on every panoramic radiograph whenever possible, five sites in the maxilla and seven sites in the mandible. Results. In the maxilla all vertical measurements distance were significantly greater in the edentulous men than in the edentulous women (p<0,05). In the mandible all vertical measurements distance were significantly greater in the edentulous men than in the edentulous women (p<0,05). Conclusion.The results of this study may guide clinicians to make primer decision of implant insertion area for implant supported prosthesis in edentulous patients

Assessment of the Level of Maxillary Sinus Floor in Dentulous, Edentulous and Free End Cases on a Sample of Malay Population Using Orthopantomogram

“…Another previous study coincides with this result which observed the reduction was more pronounced in males than in females [20]. Otherwise, another studies reported the reduction was significantly more in females than males [13,21].…”

Does Implant Fixed Restoration Can Reverse The Physiological Route Of Mandibular Bone Resorption Of The Posterior Edentulous Area For The Completely Edentulous Patients?: Systematic Review

“…[25] Changes regarding the maxillary arch are not the concern of this review .however; it should be given a great concern as the unfavorable distribution of forces of restoration may contribute in the upper arch changes. [3,9,26] panoramic radiographs have been reported to be sufficiently reliable to evaluate the available bone height in the area of posterior mandible. [27][28][29] In this review measuring of the bone height changes was done using the proportional method introduced by Wilding et al [30] The author considered the changes of the proportional area measurement could represent the changes of the alveolar ridge height.…”

Chitosan Coating on Silica-Modified Polymethyl Methacrylate for Dental Applications

“…However, rather frequently, removable dentures are inserted immediately after tooth extraction to preserve esthetics, speech, and jaw relation, as well as to protect the alveolar coagulum. The U-shaped profiles in this study with side walls up to 90 • angulation simulated the geometry of well-preserved alveolar ridges as they might be expected when extracting broken down teeth [16,17].…”

“…The intaglio U-shaped profiles corresponded in their dimensions to average sized alveolar ridges [16,17] with the purpose of simulating the shape of intaglio removable denture surfaces. All cubes were made from PMMA (Palapress, Heraeus-Kulzer, Hanau, Germany) according to manufacturer's instructions (powder to liquid ratio 10 g to 7 mL, mixing time 15 s at 23 • C).…”
