Impact of vertical loading on the implant‐bone interface

Abstract

Removal of cemented implant restorations seems not to have an impact on the mechanical implant stability, but seems to increase bone remodeling activity.

Effect of ultraviolet photofunctionalization of dental titanium implants on osseointegration

“…During all surgical interventions, the animals were initially sedated with an intramuscular injection of 4% (0.04 g/ml) azaperone (4 mg/kg BW of the minipigs, Stresnil, Jannsen-Cilag, Neuss, Germany), followed by an intramuscular injection of 10% (0.1 g/ml) ketamine (10 mg/kg BW, Bremer Pharma, Warburg, Germany) and 0.5% (5 g/L) midazolam (1.8 mg/kg BW, Braun, Melsungen, Germany). Intubation anesthesia was conducted using Isoflurane (Isofluran CP, CP Pharma GmbH, Burgdorf, Germany) (Mehl et al, 2013). After applying a local anesthetic in the upper and lower jaw (Ultracain DS forte, Hoechst, Frankfurt a. M., Germany), a dental cleaning was performed and all premolars and the first molars were removed.…”

Preparation of biological samples containing both metallic and organic structures for SEM

“…In a previous study 2,14 rabbits were subjected to osseointegrated implant placement in the tibia followed by low-level laser therapy exposure and SEM and micro-Raman spectroscopy assessment of bone-implant specimens. In this investigation, samples were sectioned without prior resin embedding.…”

“…This yields clear, easily distinguishable images of the bone and implant surfaces, enabling measurement or any other assessments of a topographic nature. Another similar method was described in a recent study of implant placement in the pig calvaria 14 , in which samples were resin-embedded, sectioned, and polished to enable high-definition imaging. With this technique, resin embedding is mandatory, which ensures the quality of later sample preparation.…”

“…These methods are not inapplicable to samples containing organic tissue 13 . A recent study used a method involving embedding of specimens in thermochemically cured resin to facilitate lengthwise sectioning and sample preparation 14 .…”

The dynamic interface: A review

“…Implant placement with high insertion or low insertion torques also has an effect on bone resorption around the implant. [13] Placement of implants with high insertion torques doubles this zone of dead and dying osteocytes, thus increasing the microfractures and bone resorption around the implant. [14]…”
