Computer-based automatic classification of trabecular bone pattern can assist radiographic bone quality assessment at dental implant site

Abstract

Computer-aided trabecular bone pattern assessment based on morphometric parameters could assist objectivity in clinical bone quality classification.

Relationship between trabecular bone architecture and early dental implant failure in the posterior region of the mandible

“…In the current study, morphometric bone parameters from a high‐resolution CBCT were used to account for the full 3D trabecular structure. Previous studies have shown that trabecular bone morphometric parameters can be used in cluster analysis to automatically distinguish bone types (Nicolielo et al, ). Based on these parameters, an automatic classifier distinguished between three types of 3D trabecular pattern, namely sparse, intermediate, and dense.…”

“…The morphometric bone parameter selection was based on our previous work (Nicolielo et al, ) in which linear discriminant analysis was used to find the best combination of morphometric parameters separating trabecular bone in three bone types: (i) sparse—related to a loose bone structure, (ii) intermediate—related to a well‐structured trabecular bone, and (iii) dense bone types—related to a massive bone area with little space between the trabeculae (Figure ).…”

“…A recent study has shown that when these morphometric parameters are linked to machine learning algorithms, they can be used to automatically distinguish three types of trabecular networks on CBCT scans of cadavers, for example, sparse, intermediate, and dense trabecular bone structures. In contrast to a subjective radiological evaluation performed by dentomaxillofacial radiologists, this automatic computer‐assisted method is objective and achieves a two to three times higher accuracy (Nicolielo, Van Dessel, van Lenthe, Lambrichts, & Jacobs, ). However, it still remains a matter of debate how the trabecular pattern can influence the outcome of the implant.…”

The Anatomical Conditions of the Alveolar Process of the Anterior Maxilla in Terms of Immediate Implantation—Radiological Retrospective Case Series Study

“…All these variables have a significant impact on the conditions and goals of the procedure and should be recognized and taken into account at the planning stage [ 10 , 15 , 20 , 21 , 22 , 29 , 30 , 32 , 46 ]. Current literature describes bony conditions for immediate implants [ 20 , 31 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 47 ]. Some of them focus primarily on internal bone structure and bone density [ 36 , 39 , 41 , 42 ].…”

“…The post-extraction socket orifice is the only entry, and therefore, the study of the most commonly encountered patterns of bone anatomy in this maxillary region is desirable. In the available literature, there are a few publications on the shape and quality of bone of the alveolar process, and there is a great need to describe the alveolar bone typical anatomy directly after tooth extraction in terms of the possibility of immediate implantation [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. In an animal model, immediately after a tooth extraction, the molecular and histologic study by Marconcini et al reported that myofibroblasts were up-regulated in the first 15-days of the healing period; thus, the excessive tension of these cells during the epithelial closure of the socket may be managed by the use of collagen, an immediate implant placement, or a provisional prosthesis [ 45 ].…”
