Measuring the Effect of Intra-oral Implant Rehabilitation on Health-related Quality of Life in a Randomized Controlled Clinical Trial

Abstract

The importance of assessing the impact of treatments for chronic conditions on an individual's quality of life has been well-established. In this randomized clinical trial, oral-health-related quality of life, measured with the Oral Health Impact Profile (OHIP), was compared between two groups of edentulous patients. One group (n = 54) received mandibular implant-supported overdentures, and the other group (n = 48) received conventional dentures. Assessments were performed pre-treatment and two months after the prostheses were delivered. The multivariate model showed that implant treatment was significantly associated with lower post-treatment OHIP scores (p = 0.0002), indicating a better quality of life. In addition, pretreatment OHIP scores, treatment allocation, age, sex, and marital status explained 31% of the variation in post-treatment OHIP scores (F = 0.0001). These results suggest that implant treatment provides significant short-term improvement over conventional treatment in oral-health-related quality of life.

Oral health-related quality of life in partially edentulous patients before and after implant therapy: a 2-year longitudinal study

“…For the latter class of patients, the two main options were removable or fixed partial dentures. In recent years, implant therapy has achieved more importance and significance thanks to a higher successful rate, new biocompatible and bone-stimulating materials, advanced technologies and the optimal effects on OHRQoL reported by patients themselves (14). This was been clearly underlined by the fact that patients who received conventional removable dentures reported little satisfaction and only modest improvements in the quality of life in comparison with patients rehabilitated with implant-supported partial dentures (15,16).…”

“…Strassburger et al (17) reviewed the impact of implant and prosthodontic treatments on OHRQoL and patient satisfaction, concluding that research in the field of patient-based outcomes has concentrated on dental implant treatment for edentulous patient, but other guiding indications for implant therapy are not well listed. With respect to chewing, bite force, function, aesthetic, dental health and self-image, implantsupported removable dentures have provided greater improvement of oral health (14)(15)(16). Selection of the specific psychometric instrument allows to assess OHRQoL and to evaluate whether implant-supported partial dentures restore the oral function and, at the same time, make patients satisfied.…”

The effect of a domiciliary denture service on oral health related quality of life: a randomised controlled trial

“…9 More recently, studies using validated quality of life measures have assessed the impact of new prostheses on the oral health related quality of life (OHQoL) of edentate patients. [10][11][12][13][14][15] Most studies have com pared outcomes from implant retained mandibular overden tures against conventional complete dentures. Non-randomised studies have reported improved OHQoL for participants who received new conventional complete dentures.…”

“…Somado a isso, a prótese total mandibular está sob influência de muitos grupos musculares, o que, por sua vez, dificulta a retenção e a estabilidade tornando essas próteses uma fonte de desconforto para muitos pacientes (Van Waas, 1990;Boerrigter et al, 1995;Awad et al, 2000;Feine et al, 2002;Regis et al, 2013). Muitos portadores de prótese total mal adaptada mostram evidências de alterações patológicas em decorrência do seu uso, como a estomatite protética, hiperplasias teciduais e queilite angular (Carlsson, 1998).…”

“…Desde então, próteses suportadas e/ou retidas por implantes se tornaram uma alternativa viável à reabilitação protética convencional de arcadas desdentadas, particularmente da mandíbula. Muitos estudos têm demonstrado que, quando indicadas apropriadamente, próteses sobre implantes promovem melhoria das funções orais, como a mastigação e a fala, além de melhora da qualidade de vida associada à saúde bucal e da satisfação dos pacientes (Geertman et al, 1999;Awad et al, 2000;Thomason et al, 2003;MacEntee et al, 2005;Allen et al, 2006;Zitzmann e Marinello, 2006;Van der Bilt et al, 2010a;Borges et al, 2011;Burns et al, 2011;Sun et al, 2014). Além disso, evidências preliminares demonstram um efeito positivo sobre o consumo de nutrientes e seleção de alimentos mais duros, como carnes, vegetais e frutas, quando pacientes recebem esse tratamento no lugar de próteses totais convencionais (Morais et al, 2003;Tajbakhsh et al, 2013), ainda que esta questão seja controversa (Hamdan et al, 2013;Khoo et al, 2013).…”
