The effect of maximum bite force on marginal bone loss of mini‐implants supporting a mandibular overdenture: a randomized controlled trial

Abstract

No relationship was found between mBF and MBL for patients wearing overdentures retained on mini-implants using bar or ball attachment systems.

Mechanical response comparison in an implant overdenture retained by ball attachments on conventional regular and mini dental implants: a finite element analysis

“…Two mesh models of overdentures supported using two RDIs and four MDIs were generated using quadratic tennode tetrahedral structural solid element (Solid 187) with hyper-elastic and lager deformation capabilities after the mesh convergence test while controlling for strain energy An important caveat of reduced diameter implants is that MDIs are weak because of their smaller diameter compared to conventional RDIs and are thus subject to fracture or deformation (Petrie & Williams 2005;Allum et al 2008;Jofré et al 2010;Wada et al 2012;Takagaki et al 2014). The bones that must carry mechanical loads adapt their strength to the load applied by bone modeling/remodeling.…”

“…Therefore, the minimal surgical intervention using mini dental implants (MDIs) has been suggested to reduce the surgical complexity and morbidity for elderly patients. The use of regular sized implants (>3 mm in diameter) would require bone reshaping or grafting (Siddiqui et al 2006;Christensen 2008;Jofré et al 2010). The advantages of MDIs are that they can be used with the minimally invasive surgery, placed within narrow or otherwise constrained sites, and offer a far more economical solution (Takagaki et al 2014).…”

“…They bring considerable benefits, including increased denture stability, functional efficiency, comfort and quality of life (Preoteasa et al 2010). Evidences indicate that a two conventional RDIs retained overdenture should become the first choice for standard treatment of edentulous mandibles (Jofré et al 2010).…”

<i>Overdentures </i>mandibulares retidas por mini-implantes ou implantes convecionais: avaliação da função mastigatória e colonização microbiana

“…Implantes com dimensões reduzidas, ou mini-implantes, têm sido utilizados como implantes temporários para o suporte de próteses removíveis provisórias durante a osseointegração de implantes convencionais, na restauração de dentes unitários, e para a retenção de overdentures (Bohsali et al, 1999;Vigolo e Givani, 2000;Petrungaro e Windmiller, 2001;Mazor et al, 2004;Kwon et al, 2005;Ohkubo et al, 2006;Siddiqui et al, 2006;Dilek e Tezulas, 2007;Jofré et al, 2010aJofré et al, , 2010bJofré et al, , 2010c. Diferentes terminologias são encontradas na literatura para designar implantes com diâmetro menor do que os tradicionalmente utilizados.…”

“…Uma busca por estudos que fornecessem informações de alto nível de evidência referentes à efetividade dos mini-implantes para retenção de overdentures mandibulares no tratamento de pacientes desdentados totais, nas bases de dados MEDLINE (via OVID), EMBASE e Cochrane CENTRAL, resultou em apenas 18 títulos. Destes, apenas uma revisão sistemática da literatura (Bidra e Almas, 2013) e três relatos do tipo ensaio clínico prospectivo randomizado foram encontrados (Jofré et al, 2010a(Jofré et al, , 2010b(Jofré et al, , 2010c …”
