“…The average implant stability quotient after osseointegration is generally 70 and the acceptable implant stability quotient range lies between 55 and 85 [46]. However, the implant stability quotient is influenced by various clinical and biological factors including bone quality and quantity, healing time, implant location, implant design and the used measuring devices [47,48]. The implant stability quotient should therefore be considered as a supplementary instrument to the clinical and radiographic examination [49].…”

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.

“…The decrease and subsequent increase in the stability of control group were attributed to remodeling during bone healing. It reflects that CGF may affect the initial stability of transplant by accelerating the osseointegration process [ 39 ]. In addition, CGF contains high concentration of growth factors, platelets and fibrin, which has great tensile strength, agglutination and adhesion, and can provide stability for the transplant to a certain extent.…”

Objective The purpose of this study was to apply concentrated growth factor (CGF) to the transplanted area with inflammation, to observe the clinical effects of CGF on the inflammation area assisted by 3D printing technology. Methods A total of 52 compromised mandibular first or second molar with chronic periapical lesions were transplanted with mature third molars. The patients were divided into CGF group (n = 26) and control group (n = 26) and transplanted into fresh extraction sockets with or without CGF. All the patients underwent clinical and radiographic examinations during the follow-up. Results Average surgery and extra-oral time were 39 min (± 7.8) and 42 s (± 10.2). The success rates of CGF group and control group were 100% and 92.3% respectively. Most of the periapical lesions in CGF group healed completely within 3 months, which was significantly faster than control group. The initial stability of CGF group was better than control group immediately after operation, and the degree of pain in CGF group was lower than control group on the 1st and 3rd day after operation. Conclusions The application of CGF in recipient site with chronic periapical lesions can accelerate the regeneration of alveolar bone and the healing of inflammation, greatly shorten the healing period. Meanwhile, CGF help to reduce postoperative pain and reaction at the early stage of healing and increase the success rate of autogenous tooth transplantation (ATT). Additionally, the use of 3D printing model can greatly reduce the extra-oral time of donor teeth.

“…These findings could be due to the fact that secondary stability was measured 4 weeks post-placement. Huang et al 2020 [ 11 ] reported that the reason for these controversial views in the literature may be the subjective and inaccurate method used to determine bone quality; thus, the classification of bone quality in investigations remains variable [ 40 ].…”

“…One advantage of this study was the standardization of the surgical protocol, in order to avoid the effect of different IT in our results. The IT was always 40 Ncm, following numerous reports in the literature recommending this level of torque to achieve adequate primary stability [ 11 , 44 , 45 , 46 , 47 ]. Likewise, the implant length was always 10 mm, and it is well documented that implants ≥10 mm provide good stability outcomes [ 48 , 49 , 50 , 51 , 52 ] and allow immediate loading with satisfactory results [ 53 , 54 , 55 ].…”

“…Over the past few years, resonance frequency analysis (RFA) has been used to determine implant stability [ 10 , 11 ]. This non-invasive diagnostic technique yields a quantitative estimation of implant stability by applying magnetic impulses on a metallic transducer (peg) previously screwed to the implant and transforming them into an electromagnetic response, measured in KHz [ 12 ].…”

Implant stability is one of the main indicators of successful osseointegration. Although it has been measured in numerous studies, there has been little research on implant stability in regenerated bone. The study compares primary and secondary stability between implants placed in regenerated versus native bone and evaluates the influence of bone quality on the results. Sixty implants were placed in 31 patients: 30 implants inserted in native bone (non-regenerated) after a healing period of at least 6 months post-exodontia and 30 inserted in regenerated bone at 6 months after grafting with xenograft. Resonance frequency analysis (RFA) was used to obtain implant stability quotient (ISQ) values at baseline (implant placement), 8 weeks, and 12 weeks. Statistically significant differences were found between implants placed in regenerated bone and those placed in native bone at all measurement time points (p < 0.05). ISQ values were significantly influenced by bone quality at baseline (p < 0.05) but not at 8 or 12 weeks. Greater stability was obtained in implants placed in native bone; however, those placed in regenerated bone showed adequate primary and secondary stability for prosthetic loading. Bone quality influences the primary but not secondary stability of the implants in both native and regenerated bone.
