“…The results improved when maxillary implant overdentures were made as a planned treatment following strict protocols 13. Nevertheless it is evident that maxillary implant overdentures present a number of different challenges compared to the predictable benefits of mandibular 2-implant overdentures 46,47. Systematic reviews concluded that maxillary overdentures on 4 or more implants in a splinted construction provided high survival (> 95% for the first year) both for implants and overdenture 14,48.…”

PURPOSETo present a literature review on implant overdentures after a brief survey of bone loss after extraction of all teeth.MATERIALS AND METHODSPapers on alveolar bone loss and implant overdentures have been studied for a narrative review.RESULTSBone loss of the alveolar process after tooth extraction occurs with great individual variation, impossible to predict at the time of extraction. The simplest way to prevent bone loss is to avoid extraction of all teeth. To keep a few teeth and use them or their roots for a tooth or root-supported overdenture substantially reduces bone loss. Jaws with implant-supported prostheses show less bone loss than jaws with conventional dentures. Mandibular 2-implant overdentures provide patients with better outcomes than do conventional dentures, regarding satisfaction, chewing ability and oral-health-related quality of life. There is no strong evidence for the superiority of one overdenture retention-system over the others regarding patient satisfaction, survival, peri-implant bone loss and relevant clinical factors. Mandibular single midline implant overdentures have shown promising results but long-term results are not yet available. For a maxillary overdenture 4 to 6 implants splinted with a bar provide high survival both for implants and overdenture.CONCLUSIONIn edentulous mandibles, 2-implant overdentures provide excellent long-term success and survival, including patient satisfaction and improved oral functions. To further reduce the costs a single midline implant overdenture can be a promising option. In the maxilla, overdentures supported on 4 to 6 implants splinted with a bar have demonstrated good functional results.

ÖZET GİRİŞAltmışbeş yaş üstü bireylerin popülasyondaki oranı her geçen gün artmaktadır. Farklı ülkelerde farklı sıklıkta gö-rülmesine rağmen, bu popülasyondaki bireylerde görü-len diş eksiklikleri ve alveol kemiklerinde oluşan rezorbsiyon da yaşlanma ile birlikte artış göstermektedir. Mevcut dişlerin çeşitli nedenlerle kaybı sonucunda tam dişsizlik kaçınılmaz hale gelmektedir. Geleneksel tam protez kullanan dişsiz hastalar fonksiyon sırasında özel-likle alt protezlerinin stabilitesinin ve tutuculuğunun yetersiz olması nedeniyle olumsuz tecrübelere sahiptirler. 1-3Daha önceleri konvansiyonel tam protezler, tam diş-sizliklerde sıklıkla en çok tercih edilen tedavi yöntemi iken günümüzde implant üstü overdenture'lar dişsizliğin giderilmesinde birinci seçenek olarak sunulmaktadır. 2İmplant üstü overdenture'lar ile konvansiyonel tam protezlerin karşılaştırıldığı çok sayıda çalışmada implant üstü overdenture kullanan hastalarda, çiğneme etkinliği, protez stabilitesi, protez retansiyonu ve estetiğin daha tatminkar olduğu ve buna bağlı olarak hasta memnuniyetinin çok daha fazla olduğu rapor edilmiştir.4-11 Alt çene tam dişsizlik durumunda implant destekli overdenture için maliyet ve hasta memnuniyeti dikkate alındı-ğında en az iki implanttan destek almak gerekmektedir. 2Ancak üst çenede implant destekli overdenture'lar için belirli bir implant sayısı belirtmeye yeterli kanıt literatürde bulunmamaktadır. [12][13][14] İmplant üstü overdenture'larda implant ile protez arasındaki bağlantı, hassas bağlantı yapısındaki bir tutucu sistem aracılığı ile sağlanmaktadır. Bu tutucu sistemler iki ana başlık altında toplanabilir.

“…Most complaints are related to retention and stability of dentures especially in mandibles. For these patients implant-supported overdentures can be an effective treatment (1)(2)(3). Implant-supported overdentures compared with complete dentures have more retention and stability and have less cost than complete implant-supported fixed prosthesis, and even years after, more implants can be added to the treatment plan.…”

Background: Implant-supported overdentures could have many benefits for patients, especially in the lower jaws. As a matter of fact, the most common reason for prescribing mandibular overdenture is dissatisfaction of patients with mandibular dentures usually because of a lack of retention, stability and function and speech difficulties. On the other hand, patients' expectations of overdenture treatments are their main disadvantage. Objectives: The aim of this study was to evaluate the satisfaction of patients who had received mandibular implant supported overdenture treatment with different number of implants. Patients and Methods: This study was a descriptive cross-sectional study. Twenty-five patients with a mean age of 62.7 years who had received mandibular implant supported overdenture treatment at the dental school of Hamadan University of Medical Sciences were enrolled. Among these patients, six had overdentures supported by one implant, nine had overdentures supported by two implants, two had overdentures supported by three implants, five had overdentures supported by four implants and three had overdentures supported by five implants. The visual analogue scale (VAS) questionnaire was used to evaluate the general satisfaction, comfort, esthetic, fitness, satisfaction of chewing and social communication, and the data was analyzed by the analysis of variance (ANOVA) test. Results: All patients in all five groups were satisfied with their overdentures; however there was no significant relationship between the number of implants and fitness (P = 0.446), esthetic (P = 0.843), comfort (P = 0.805), satisfaction of chewing (P = 0.133), social communication (P = 0.322) and general satisfaction (P = 0.493). Conclusions: There was no difference in satisfaction level of patients who had received mandibular overdentures with different number of implants.
