Effect of Single and Contiguous Teeth Extractions on Alveolar Bone Remodeling: A Study in Dogs

Abstract

Contiguous teeth extraction caused significantly more alveolar ridge bone loss as compared with when a single tooth is extracted.

Alveolar Bone Remodeling Around Immediate Implants Placed in Accordance With the Extraction Socket Classification: A Three‐Dimensional Microcomputed Tomography Analysis

“…This study shows that extraction of contiguous multiple teeth is associated with significantly more buccal bone remodeling around immediate implants compared to implants placed in single tooth extraction sites. This is in agreement with the studies that emphasized the importance of the interdental bone blood supply to the buccal bone 19,20 …”

“…According to Al‐Hezaimi et al, 19 the extraction socket may still be receiving blood supply from the adjacent interdental bone, thereby reducing the rate of buccal bone resorption. The present study supports the results by Covani et al 16 to an extent, because immediate implants placed in a single tooth extraction site (ESC‐1) showed slight buccal bone loss compared to immediate implants installed in sites with multiple contiguous teeth extractions (ESC‐2 and ESC‐3) 20 . With reference to jaw location (either maxilla or mandible), no significant difference in alveolar bone remodeling around immediate implants **** were observed in any group.…”

“…Bone remodeling is a complex process in which old bone is removed by the process of resorption and is replaced by new bone. It has been suggested that, after tooth extraction, the blood vessels to the bone walls are severed, thereby causing bundle bone resorption; 4 however, other reports 19,20 have shown that the interdental bone blood supply to the buccal bone is also a significant factor in this regard. This loss of blood supply to the bone may cause death of the osteocytes and necrosis of the surrounding mineralized tissue.…”

Bone morphology changes around two types of bone‐level implants installed in fresh extraction sockets – a histomorphometric study in Beagle dogs

“…This was done by purpose, as bone alterations following tooth extraction has been the topic of earlier investigation by another group at King Saud University (Al‐Askar et al. ). A similar comment has to be made about the lack of a positive control (crestal bone alteration after immediate implant installation).…”

Microcomputed Tomographic Analysis of the Alveolar Ridge Alteration around Extraction Sites with and without Immediate Implants Placement: In Vivo Study

“…Tooth extraction is a traumatic procedure that jeopardizes the surrounding alveolar bone and soft tissues. Healing of the extraction socket involves several biochemical and histologic events that may alter alveolar bone architecture 1–6 . It is known that by the fourth week of extraction, the extraction socket fills with bundle bone (an immature bone that is supplied entirely and solely by ligaments and tendons) 3–5 .…”
