Nowadays there is a general consensus related to the stability of dental implants during bone repair. The implant anchorage in the bone is very important for the stability of the element that has to support much pressure when under use. This stability is attained by bone modeling and remodeling processes. As it is known, the implant/bone interface does not present the ideal result expected by every professional. The possibility of stimulation of the bone formation at the interface and around titanium implants is based on the reaction of the bone to trauma due to the surgical procedure. This bone reaction leads to bone repair during healing. The purpose of this study is to analyze the efficiency of bone tissue labeling through polyfluorochrome sequential labeling during remodeling or neo-formation processes after the placement of smooth threaded implants used in dentistry. This work demonstrates the possibility of periodic deposition of bone identification around titanium osseointegrated implants. It was concluded that the polyfluorochrome sequential labeling is an important tool to identify bone modeling and remodeling after the insertion of titanium implants inside rabbit's tibias at different periods of time.

Objectives: Previous efforts led to the development of two different polymeric biomaterials for periodontal regeneration with antibacterial photodynamic surface activity. The present study aimed to investigate osseointegration and bone formation of both materials in an ovine model.
Methods: Both biomaterials: 1) urethane dimethacrylate-based Biomaterial 1 (BioM1) and 2) tri-armed oligoester-urethane methacrylate-based Biomaterial 2 (BioM2) are enriched with beta-tri-calcium phosphate and the photosensitizer meso-tetra(hydroxyphenyl)chlorin (mTHPC).

Background: The healing process following tooth extraction results in alveolar ridge resorption. The dimensional changes may complicate the subsequent implant procedure. Socket preservation using absorbable collagen membranes or a combination of membranes with calcium phosphate cement (CPC) particles might ensure that the alveolar ridge retains a suitable morphology for implant placement.

Strontium-containing hydroxyapatites (Sr-HA) combine the desirable bone regenerative properties of hydroxyapatites (HA) with anabolic and anti-catabolic effects of strontium cations. In the present work, a series of Sr(y)HA [Sr(y)Ca(10-y)(PO4)6(OH)2; y = 0, 0.5, 1, 2] coatings on titanium are produced by micro-arc oxidation (MAO), and the effects of the in vivo osseointegration ability of the coatings are investigated by using a rabbit model.

Objectives: The aim of this study was to evaluate the osseointegration of loaded orthodontic microscrews at different cortical bone thickness (CBT) sites.
Study Design: Forty-eight microscrews were inserted bilaterally in the tibias of 12 beagles, and divided into thick and thin CBT group. After 1, 3, 5, and 7 weeks, the dogs were killed and bone-screw specimens prepared for polyfluorochrome sequential labeling, microscopic computerized tomography (μCT) analysis, and biomechanical pull-out testing.

Spontaneous early exposure of submerged implants during the healing phase as a factor for early crestal bone loss around the implants is still being controversially discussed. The aim of this study was to examine the potential impact of dehiscences on the osseointegration process of acid-etched dental implants with a shortened healing period in the maxilla. Five animals received a total of 15 titanium implants 8 weeks postextraction.
