Influence of the Thermal Treatment to Address a Better Osseointegration of Ti6Al4V Dental Implants: Histological and Histomorphometrical Study in a Rabbit Model

Abstract

Background Pure titanium continues to be the first choice for dental implants and represents the gold standard for their biocompatibility and physical and mechanical characteristics, while the titanium alloy (Ti6Al4V) has good mechanical properties. The surface structure of the titanium oxide layer formation on the surface influences and improves the bone response around dental implants. Purpose The purpose of this study is to evaluate the influence of a thermal treatment of Ti6Al4V implant surfaces and the bone healing response in a rabbit model. Methods Altogether sixteen implants with same design were inserted into the distal femoral metaphysis. A screw (13 mm long, 4 mm in diameter) was inserted in an implant bed. Each rabbit received two implants, one in the left femur and one in the right femur. The samples were histologically and histomorphometrically evaluated at 8 weeks. Results A statistically significant difference (p = 0.000034) was present histologically in the percentages of bone-implant contact (BIC) between the test group (BIC = 69.25±4.49%.) and control group (BIC = 56.25 ± 4.8%) by one-way analysis of variance (ANOVA). Significance was set at p ≤ 0.05. Conclusions The outcome of the present study indicates a novel approach to improving bone healing around titanium implants.

The Effects of Erbium-Doped Yttrium Aluminum Garnet Laser (Er: YAG) Irradiation on Sandblasted and Acid-Etched (SLA) Titanium, an In Vitro Study

“…Moreover, the color of the disks changed significantly with the increase of power laser irradiation. It is well known that titanium is covered in the external layer by titanium oxides, like TiO 2 , TiO, and Ti 2 O 3 [39]. Our findings suggest that laser irradiation increased the oxide layer of the TiO 2 and TiO.…”

A Novel Technique to Increase the Thickness of TiO₂ of Dental Implants by Nd: DPSS Q-sw Laser Treatment

“…Laser treatment proved to increase TiO 2 layers and influence bone healing with active mineralization progressions on the implant surfaces. A greater thickness of the oxide layer on the surface is desirable because it increases the bone-implant contact [28] and reduces the bacterial biofilm [14]. Titanium develops an oxide layer when exposed to liquids or air, which reduces its reactivity and improves bone-implant contact [28].…”

Titanium develops an oxide layer when exposed to liquids or air, which reduces its reactivity and improves bone-implant contact [28]. The bioactive implant enhances the formation of hydroxyapatite on the surface of the implant in contact with body fluids [29].…”

On the Future Design of Bio‐Inspired Polyetheretherketone Dental Implants

“…In literature, over 1300 types of commercial dental implants have been reported, in varying form, material, interface properties, and geometries . Since more than 60 years, the use of titanium or titanium alloys is state‐of‐the‐art and still the golden standard in dental applications worldwide . Introduced in the early 50s, this metal‐based implant material is used in the majority of dental implant surgeries, using a dental implant, which is characterized by the above‐mentioned screw design.…”
