Back‐scattered electron imaging and elemental analysis of retrieved bone tissue following sinus augmentation with deproteinized bovine bone or biphasic calcium phosphate

Abstract

The beta-TCP component of BCP may be gradually substituted by calcium-deficient hydroxyapatite over the healing period. This process and superficial degranulation of BCP particles may influence the progress of resorption and healing.

SEM-EDX Study of the Degradation Process of Two Xenograft Materials Used in Sinus Lift Procedures

“…To investigate in detail the distribution of Ca/P in selected areas and individual biomaterial particles, line scans were carried out with a selection of different points from the implant through the middle to the periphery of samples to detect changes in the Ca/P ratios (see Figure 5), following the recommendation of Lindgren [47]. The EDX analysis of the residual graft material particles in the retrieved tissue revealed Ca/P to be in every variable relative proportion.…”

Use of autogenous bone and beta-tricalcium phosphate in maxillary sinus lifting: a prospective, randomized, volumetric computed tomography study

“…This increased CBV of b-TCP confirms the findings of studies reported in the literature that have shown its rapid resorption. 2,27,[37][38][39] This may be an advantage of b-TCP over other bone substitutes, which often present a long duration of bone repair and a theoretically high risk of infection as the main negative points. 40 The mean graft resorption observed in the present study may indicate the need for overcorrection, i.e.…”

A Human Clinical, Histological, Histomorphometrical, and Radiographical Study on BiphasicHA‐Beta‐TCP30/70 in Maxillary Sinus Augmentation

“…Nowadays, CaP ceramics of various phase compositions, different formulations (bone cements, granulates, or blocks), and several sizes and shapes are used . Most of the studies available report on 60% HA and 40% TCP . They state that the dissolution of TCP might lead to more interparticular space for new bone formation.…”
