During the past decade, the use of osseointegrated implants as a foundation for prosthetic replacement of missing teeth has become highly predictable and successful. SPT(Supportive Periodontal Therapy) identified as regular visits to the therapist for periodontal control and maintenance in a well-organized scheme, the number of appointments per year following a pre-designed subject-tooth/implant-site risk assessment method. Peri-implant disease was a frequent finding in subjects having natural healthy dentition and in subjects without periodontitis. Supportive periodontal program were found to be strongly related to implant survival. This study demonstrates that regular maintenance reduces the risk for peri-implant inflammation significantly as compared with irregular maintenance. This underlines the value of the SPT in enhancing the long-term outcomes of implant therapy, particularly in subjects affected by periodontitis, in order to control reinfection and limit biological complications. It is highly recommended to maintain implant patients under a strict supportive periodontal treatment protocol that might contribute to implant survival, and regular maintenance reduces the risk for periimplant inflammation significantly as compared with irregular maintenance. Ideally, patients may be informed on the beneficial effect of a regular patient-related post-therapy care before implant insertion.

Objectives: The purpose of this study is to understand the practices of the dental implant maintenance care according to knowledge and attitude toward dental implant in the dental service consumers. Methods: T-test, ANOVA, and cross tabulation were carried out to understand the knowledge and attitude toward the dental implant, the experiences of the treatments, and the practices of their maintenance care depending on the general characteristics and the oral-health education experience. The collected data were analyzed using by SPSS Windows Program 23.0. Results: The actual state of the implant maintenance care was revealed to be high in the use of oral care products with 83.9% and in the professional maintenance care with 86.0%. In terms of the implant-related experiences, the participation and the participation frequency in the professional maintenance care were resulted to be higher especially in those with more cases of surgical procedures and in those with more failure experiences. Examining the practices of management according to knowledge and attitude toward dental implant, the higher in knowledge and attitude led to the higher uses of oral care products. The periodically professional maintenance care was indicated to be received even if being taken high management cost. Conclusions: Effective education methods and programs are necessary to be developed and executed so that information and knowledge can lead the correct practices in the dental service consumers.

PURPOSE. The aim of this systematic review was to address treatment outcome according to attachment systems for mandibular implant overdentures in terms of implant survival rate, prosthetic maintenance and complications, and patient satisfaction. MATERIALS AND METHODS. A systematic literature search was conducted using PubMed and hand searching of relevant journals considering inclusion and exclusion criteria. Clinical trial studies on mandibular implant overdentures until August, 2010 were selected if more than one type of overdenture attachment was reported. Twenty four studies from 1098 studies were finally included and the data on implant survival rate, prosthetic maintenance and complications, patient satisfaction were analyzed relative to attachment systems. RESULTS. Four studies presented implant survival rates (95.8 - 97.5% for bar, 96.2 - 100% for ball, 91.7% for magnet) according to attachment system. Ten other studies presented an implant survival rate ranging from 93.3% to 100% without respect to the attachment groups. Common prosthetic maintenance and complications were replacement of an assay for magnet attachments, and activation of a matrix or clip for ball or bar attachments. Prosthetic maintenance and complications most commonly occurred in the magnet groups. Conflicting findings were found on the rate of prosthetic maintenance and complications comparing ball and bar attachments. Most studies showed no significant differences in patient satisfaction depending upon attachment systems. CONCLUSION. The implant survival rate of mandibular overdentures seemed to be high regardless attachment systems. The prosthetic maintenance and complications may be influenced by attachment systems. However patient satisfaction may be independent of the attachment system.

PURPOSE. The aim of the current study was to analyze treatment concepts of a cohort of German dentists for planning, fabrication, and maintenance of implant-supported fixed and removable restorations. MATERIALS AND METHODS. A questionnaire including queries about experiences with implant-supported restorations as well as prosthetic and maintenance treatment concepts for supplying patients with fixed and removable implant-supported prosthetic restorations was developed and sent to 350 dental offices registered in the municipal area of Leipzig, Germany. RESULTS. An overall total of 62 returned questionnaires were included in the analyses, which relates to a response rate of 17.7%. Participating dentists were more involved in the prosthetic aspects of implant dentistry rather than surgery, while prosthetic concepts such as backward planning, digital processing, and application of all-ceramic materials were not commonly performed. Simple attachments were preferred over complex retention systems in removable implant-supported restorations. Tooth/implant-supported fixed denture prostheses as well as removable denture prostheses with supporting posterior implants were not regarded as a favorable treatment option. CONCLUSION. Within the limitations of the study, the data indicate that dentists favor simple and conventional treatment approaches in implant prosthetics. Prosthetic aspects in the planning of implant-supported restorations are often neglected. Prosthetic treatment guidelines and aspects should commonly be considered in the planning phase of implant-supported prosthetic restorations, and awareness should be increased in postgraduate education.

PURPOSE. The aim of this systematic review is to address treatment outcomes of Mandibular implant overdentures relative to implant survival rate, maintenance and complications, and patient satisfaction. MATERIALS AND METHODS. A systematic literature search was conducted by a PubMed search strategy and hand-searching of relevant journals from included studies. Randomized Clinical Trials (RCT) and comparative clinical trial studies on mandibular implant overdentures until August, 2010 were selected. Eleven studies from 1098 studies were finally selected and data were analyzed relative to number of implants. RESULTS. Six studies presented the data of the implant survival rate which ranged from 95% to 100% for 2 and 4 implant group and from 81.8% to 96.1% for 1 and 2 implant group. One study, which statistically compared implant survival rate showed no significant differences relative to the number of implants. The most common type of prosthetic maintenance and complications were replacement or reattaching of loose clips for 2 and 4 implant group, and denture repair due to the fracture around an implant for 1 and 2 implant groups. Most studies showed no significant differences in the rate of prosthetic maintenance and complication, and patient satisfaction regardless the number of implants. CONCLUSION. The implant survival rate of mandibular overdentures is high regardless of the number of implants. Denture maintenance is likely not inflenced substantially by the number of implants and patient satisfaction is typically high again regardless os the number of implants.

If the implant is planted in the wrong position or direction, it is disadvantageous for stress distribution, and it is easy to cause complications such as screw loosening, abutment fracture, and implant fracture. If the position or orientation of the implant is not good, efforts should be made to minimize the problem through proper implant prosthetic treatment. In this article, the prosthetic method for facilitating future maintenance in cases with poor implant placement or orientation will be presented.

임플란트 피개의치에서 치주적, 보철적 유지관리는 보철물과 임플란트의 장기적 성공에 매우 중요한 요인이다. 유지관리의 실패는 임플란트 주위 골소실 및 보철물이나 구성품의 파절 및 마모로 인해 보철적 실패를 유발할 수 있다. 이 증례에서는 유지관리 실패로 파절된 임플란트 피개의치의 재치료를 위해 기존의 골드 milled bar를 코발트 크롬 milled bar로 외형에 방해되지 않는 형태로 재제작하였고, 하악의 기존 고정성보철은 임플란트 주변 골흡수와 환자의 전신적 문제로 인해 전략적으로 임플란트를 선택하여 두 개의 임플란트에 CM LOC을 연결하여 임플란트 피개의치를 제작하여 재수복하였다. 결과적으로 환자의 위생관리를 수월하게 하는 디자인의, 기능적 심미적으로 장기간 유지관리에 유리한 보철물로 수복하였고 정기적인 유지관리를 시행하였다.
