Effects of calcium phosphate composition in sputter coatings on in vitro and in vivo performance

Abstract: Calcium phosphate (CaP) ceramic coatings have been used to enhance the biocompatibility and osteoconductive properties of metallic implants. The chemical composition of these ceramic coatings is an important parameter, which can influence the final bone performance of the implant. In this study, the effect of phase composition of CaP-sputtered coatings was investigated on in vitro dissolution behavior and in vivo bone response.

The Influence of implant geometry and surface composition on bone response

Abstract
Objectives: The implant design and surface modification are independent conditions that can alter the implant bone response. The objective of this study is to compare the bone response to roughened tapered and cylindrical screw–type implants with and without hydroxyapatite (HA) surface coating in the femoral trabecular bone of rabbits.

Resolution, sensitivity, and in vivo application of high-resolution computed tomography for titanium-coated polymethyl methacrylate (PMMA) dental implants

Abstract
Objectives: The aims of this study were (i) to determine the spatial resolution and sensitivity of micro- versus nano-computed tomography (CT) techniques and (ii) to validate micro- versus nano- CT in a dog dental implant model, comparative to histological analysis.

In vivo evaluation of bioactive glass-based coatings on dental implants in a dog implantation model

Abstract
Objectives: Although titanium is commonly used as a favorable bone implant material due to its mechanical properties, its bioactive and osteoconductive capacity is relatively low. Calcium phosphate ceramics, predominantly hydroxyapatite (HA), have been frequently used for coating purposes to improve the bioactive properties. In view of the suggested osteopromotive capacity of bioactive glasses (BGs), this study aimed to evaluate the effect of BG incorporation into HA coatings on implant performance in terms of bone contact and bone area.

Does Steam Autoclaving Affect the Accuracy of Implant Impression Systems?

The purpose: The aim of this in-vitro pilot study was to evaluate the effect of steam autoclaving
of the implant analog and impression coping on the accuracy of impression procedure. Materials
and methods: A master casts model was constructed, with a pair of commercially available fixtures.
Ten pairs of impression copings were used to make the impression. Implant analogs were then
attached to the copings and ten sets of duplicated casts were prepared and numbered. Baseline

Oral rehabilitation of a case of Papillon-Lefevre syndrome with dental implants

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive disorder characterized by diffuse palmoplantar keratoderma and precocious aggressively progressing periodontitis, leading to the premature loss of deciduous and permanent teeth. Full mouth rehabilitation with implant supported fixed prosthesis provides numerous advantages over the conventional denture in terms of esthetics, function, longevity of the prosthesis, and patient satisfaction.

Osseointegration of Oral Implants After Delayed Placement in Rabbits: A Microcomputed Tomography and Histomorphometric Study

Purpose: This study compared osseointegration of implants placed 14 days after implant site preparation with that of immediately placed implants in rabbit femurs. Materials and Methods: Implants were placed bilaterally in the femoral condyles of 12 rabbits. On one side, the implants were placed 14 days after osteotomy, and the other side received implants immediately after osteotomy. Healing was assessed by microcomputed tomography and histomorphometry. Results: The delayed implants (placed 14 days after osteotomy) showed better osseointegration than the immediately placed implants.

Biological response to titanium implants coated with nanocrystals calcium phosphate or type 1 collagen in a dog model

Abstract
Objective: The current study aimed to evaluate the osteogenic potential of electrosprayed organic
and non-organic surface coatings in a gap-implant model over 4 and 12 weeks of implantation
into the dog mandible.
Material and methods: Sixteen Beagle dogs received experimental titanium implants in the
mandible 3 months after removal of left premolars (P2, P3 and P4). Three types of implants were
installed in each animal: non-coated implant, nano-CaP coated implant and implant with type 1

Causes of Adverse Pregnancy Outcomes and the Role of Maternal Periodontal Status – A Review of the Literature

Abstract: Preterm (PT) and Low birth weight (LBW) are considered to be the most relevant biological determinants of newborn infants survival, both in developed and in developing countries. Numerous risk factors for PT and LBW have been defined in the literature. Infections of the genitourinary tract infections along with various biological and genetic factors are considered to be the most common etiological factors for PT/LBW deliveries.
