Comparison of two dental implant surface modifications on implants with same macrodesign: an experimental study in the pelvic sheep model

Abstract

The two surfaces proved comparable osseointegration in this sheep model.

Thermal oxidation and hydrofluoric acid treatment on the sandblasted implant surface: A histologic histomorphometric and biomechanical study

“…Real‐sized implant fixtures were tested on a sheep pelvis model as the use of miniature implants on small animal models had demonstrated conflicting results, especially in the biomechanical tests due to the restricted surface area (Pearce, Richards, Milz, Schneider, & Pearce, ; Yi et al., ). The sheep pelvis has the advantage of mimicking the mandibular bone and is free from the additional healing risks involved in the oral environment (Ernst et al., ; Plecko et al., ).…”

“…In this study, the topographical, chemical, and osseointegration characteristics of the sandblasted thermally oxidized surface (SO) TA B L E 1 Optical profilometry measurements of surface roughness on screw-type implants (measurement area: 42 × 210 in the biomechanical tests due to the restricted surface area (Pearce, Richards, Milz, Schneider, & Pearce, 2007;Yi et al, 2015). The sheep pelvis has the advantage of mimicking the mandibular bone and is free from the additional healing risks involved in the oral environment (Ernst et al, 2015;Plecko et al, 2012).…”

A rabbit maxillary sinus model with simultaneous customized‐implant placement: Comparative microscopic analysis for the evaluation of surface‐treated implants

“…Also, it can be emphasized that there was no significant difference in NBIC (%) between SLA surface implant and MA surface implant placed in tibia at 2 weeks. According to Ernst et al (), there was significant difference in BIC between titanium oxide surface (control) and SLA (experimental) 8 weeks after implant placement in iliac wings of sheep which has similar bone metabolism to human but has slower bone metabolism than rabbit whereas there was no significant difference found between two groups 4 weeks after implant placement. Richards et al (), reported that rabbit has a faster rate of new bone formation than primate and new bone formation activity was limited to periosteal regions closed to the surface of cortical bone, resulting in reduced trabecular bone structure underneath cortical bone, which was supported by the result of our study; Figures and shows new bone formation around cortical bone and limited trabecular bone formation.…”

Titanium discs coated with 3,4-dihydroxy-l-phenylalanine promote osteogenic differentiation of human bone mesenchymal stem cells in vitro

“…33 However, extremely high surface energies may hinder cell motility and subsequent cell function. 34 The optimal hydrophilicity of dental implants for best biological and clinical outcomes still remains unclear. Furthermore, DOPA-coating increases surface hydrophilicity, owing to its catechol and amine functional groups, 35 and water contact angle decreases as a function of dopamine concentration, reecting increased hydrophilicity.…”
