Implant‐retained mandibular overdentures compared with complete dentures; a 5‐years' follow‐up study of clinical aspects and patient satisfaction

Abstract

The aim of this prospective randomized controlled clinical trial was to evaluate and compare clinical aspects and satisfaction during the first year following treatment and consecutively the change in treatment during the next 4 years of follow-up. Patients were allocated to one of the following treatment modalities: an implant-retained overdenture (IRO-group, 2 endosseous implants, n = 61) or a complete denture (CD-group, n = 60). One year after placement of the denture, unsatisfied patients of the CD-group got the opportunity for a retreatment including an implant-retained overdenture. In the IRO-group 4 implants were lost during the first year and again 4 implants were lost during the next 4 years (survival rate: 93%). All patients could be re-operated successfully. In the CD-group 14 patients (23%) chose an implant-retained overdenture after 1 year. Patients of the IRO-group were significantly more satisfied than patients of the CD-group after 1 year (satisfaction score 8.3 versus 6.6, scale 1-10) and after 5 years (7.4 versus 6.4). From this study it can be concluded that endosseous implants have a high survival rate after 5-years' follow-up. Satisfaction score of the IRO-group is diminishing in time, probably because patients get used to an improved situation. After 5 years, the mean satisfaction score of the CD-group (including patients who got implants) was still lower than of the IRO-group, in spite of the opportunity to a retreatment and have implant-retained overdentures.

Comparison of patient′s satisfaction with implant-supported mandibular overdentures and complete dentures

“…In addition, he also showed that the mandibular implant-retained overdenture group performed significantly better than the complete denture group in every respect. [24,29,30] With respect to the effects on mental and daily life, the average score for mandibular implant-retained overdentures was better than for the conventional complete denture. However, there was no significant difference between the groups.…”

“…[24] According to Boerrigter's method, there are three aspects to consider when evaluating satisfaction with dentures: (1) problems with the denture itself: Any problem or complication resulting from denture usage; (2) masticating ability: Chewing performance when patients eat different kinds of food; and (3) overall denture performance: The physical and life impacts on the patient, derived from the denture.…”

In Vitro Study of Retention of Paired Press-Stud Overdenture Component Attachments

“…The mandibular two-implant overdenture has become a widely used restoration for edentulous patients, and the success of this type of restoration has been documented [1][2][3][4]. However, there has been a report of high failure rate of the retentive components used in these restorations, which seems to be related to their repeated use [5].…”

İmplant Destekli̇ Hi̇bri̇t Protezler

“…Zirkonyum alt yapılı hibrit protez 21 Hbirit protezler dişsiz hastalara geleneksel tam protezler ile kıyaslandığında pek çok fonksiyonel, estetik ve psikolojik avantaj sunmaktadır. 22,23 Bu tür protezlerin ekonomik olarak daha uygun olması, son derece estetik restorasyonların hazırlanabilmesi, okluzal kuvvetler boyunca oluşan stresleri azaltması gibi birçok avantajı vardır. 9 Bunun yanı sıra aşırı derecede rezorbe olmuş üst çene arka bölge kretlerinde açılı olarak yerleştirilecek implantlarla başarılı protezlerin yapılabilmesi mümkündür.…”
