Objectives:
Many authors’ have advocated a minimum of two implants to support a mandibular overdenture, but financial restraints specifically among the geriatric population in developing countries made this treatment plan economically difficult. Hence, this study was planned to assess the symphyseal (midline) single implant-assisted complete overdenture for patient satisfaction and masticatory performance.
Materials and Methods:
In this clinical study, 12 edentulous first-time denture wearers underwent placement of a single implant in the mandibular symphyseal region. After 1 week, new complete dentures were fabricated and delivered to the patients. Post 3 months, the denture was fixed with a nylon cap-ball attachment to the anchor implant. Patients were questioned about comparison in the level of satisfaction and complaint before loading the implant (control group) and after 1 week, 1 month, and 3 months. The implant-assisted overdenture was fabricated with the help of a questionnaire. Masticatory performance was calculated with the help of a bite force measuring device at the same time intervals. SPSS 17.0 statistical software was used to analyze the data.
Results:
It was found that single implant anchorage of the mandibular complete denture resulted in a significant increase (
P
< 0.05) in patient's subjective satisfaction and a decrease (
P
< 0.05) in complaints at the end of 3 months. There was a significant (
P
< 0.01) increase in bite force in implant overdenture after 3 months (5.459 kgf) as compared to that of the complete denture (3.406 kgf).
Conclusion:
Single implant-assisted overdenture can be an appropriate treatment modality to treat edentulousness in the geriatric population. It insinuates the remarkable improvement of prosthesis function and oral comfort with minor surgical procedures.
Denture labelling is not a new concept in either prosthetic or forensic dentistry and its routine practice has been urged by forensic dentists internationally for many years. Prosthodontists are playing very important role in forensic dentistry as they are concerned with fabrication of various prosthesis which can serve as an important tool for identification. The main objective of this article is to discuss the various methods available for denture marking along with three case reports.
Objectives:
The bone quantity and quality determine the prosthetic success outcome. This research was performed to evaluate the bone density for insertion of pterygoid implants in edentulous and dentulous participants with cone-beam computed tomography (CBCT).
Materials and Methods:
CBCT evaluation was done for 66 dentate and edentulous patients for pterygoid implants at the pterygomaxillary region. The calculation of joint width, height, and volume of bone was done. Density of the bone was evaluated at the superior and inferior aspects of the pterygomaxillary column.
Results:
It was observed that average pterygomaxillary joint height for dentulous (dentate) was −12.7 ± 7.2 mm, edentulous −12.4 ± 7.1 mm, the average pterygomaxillary joint width for dentulous was 8.15 ± 7.3 mm, and 8.13 ± 6.2 mm for edentulous. The average pterygomaxillary joint volume in dentulous participants was 279.4 ± 189.2 mm
3
and for edentulous was 254.5 ± 176.4 mm
3
. There was expressively greater density of the bone in dentulous participants over edentulous participants (
P
< 0.05).
Conclusion:
There was better bone density found in dentate participants in comparison to edentulous participants. CBCT is a recent investigative device which measures pterygoid area efficiently. Pterygoid implants may be deliberated as an alternative method for resorbed (atrophic) maxilla.
