Lateral Alveolar Ridge Augmentation with Autogenous Tooth Block Graft Compared with Autogenous Bone Block Graft: a Systematic Review

Abstract

Objectives:The objective of the present systematic review was to evaluate the current knowledge of implant treatment outcome following lateral alveolar ridge augmentation with autogenous tooth block graft compared with autogenous bone block graft prior to implant placement. Material and Methods: MEDLINE (PubMed), Embase and Cochrane Library search in combination with hand-search of relevant journals was conducted including human studies published in English through December 20, 2021. Comparative and non-comparative studies assessing lateral alveolar ridge augmentation with autogenous tooth block graft were included. Quality and risk-of-bias assessment were evaluated by Cochrane risk of bias tool, Newcastle-Ottawa Scale and GRADE system. Results: One comparative study characterized by low grade and two non-comparative studies fulfilled the inclusion criteria. No significant difference in short-term implant survival, health status of the peri-implant tissue or frequency of complications between the two treatment modalities was observed. Postoperative dimensional changes of the alveolar ridge width were significant diminished with tooth block compared with bone block (P = 0.0029). Consequently, the gain in alveolar ridge width was significantly higher with tooth block, after 26 weeks (P = 0.014). However, a higher frequency of short-term peri-implant mucositis was observed with tooth block. Conclusions: Lateral alveolar ridge augmentation with tooth block seems to be a suitable alternative to bone block. However, results of the present systematic review are based on short-term studies involving small patient samples. Further long-term randomized controlled trials are therefore needed before definite conclusions can be provided about the beneficial use of tooth block compared with bone block.

Autogenous Dentin Particulate Graft for Alveolar Ridge Augmentation with and without Use of Collagen Membrane: Preliminary Histological Analysis on Humans

“…The physical-chemical and biochemical features of the dentin and enamel matrix obtained after processing teeth derivatives with the Tooth Transformer device have been described in a recent in vitro study [14][15][16][17][18][19][20][21][22][23][24][25]. A study [22] found that the biocompatibility of demineralized dentin is even higher than the more popular xenograft bovine bone, and that demineralization increases BMP-2 and type I collagen bioavailability as compared with non-demineralized tooth derivatives.…”

“…Tooth extraction is certainly the most performed surgical procedure in dentistry, and the teeth extracted were considered waste elements. Recent clinical studies have proposed the reimplantation of the same dental elements, the partial retention of the root to allow for the preservation of the bundle bone, and the use of particulate dentin as a graft material [11][12][13][14][15][16][17][18][19][20]. Studies in humans have demonstrated the clinical efficacy and safety of the partially demineralized autogenous dentine matrix prepared chairside as a bone graft [19][20][21][22][23].…”

Tooth Graft: An Umbrella Overview

“…This heterogeneity prevents most of them from conducting a meta-analysis to determine the extent of this graft's effectiveness. In this umbrella review, 9 15 16 17 18 19 20 21 22 23 systematic/meta-analysis articles comprising 81 (23 RCTs and 58 non-RCTs) articles were included. The outcomes extracted from these umbrella studies were associated with tooth graft procedures.…”

“…However, a higher incidence of short-term peri-implantitis was observed after LARA with autogenous tooth block grafting. 20…”

“…19 Starch-Jensen et al conducted a systematic review of the clinical data on implant management after lateral alveolar ridge augmentation (LARA) with autogenous dental block grafting versus autogenous bone block grafting before implant placement. 20 Inchingolo et al studied engineered structures, such as tooth block grafts, growth factors, and light modulation applications for bone repair therapy. 21 Ramanauskaite et al analyzed clinical data regarding the effect of autogenous teeth on alveolar ridge augmentation.…”
