The width of KM (≥2 mm) had some effects on the development (i.e., at 21 days) and resolution of experimental peri-implant mucositis lesions at both abutment types.

Objectives To assess the short‐term clinical outcomes of lateral augmentation of deficient extraction sockets and two‐stage implant placement using autogenous tooth roots (TR). Material and methods A total of n = 13 patients (13 implants) were available for the analysis. At the time of tooth extraction, each subject had received lateral augmentation using the respective non‐retainable but non‐infected tooth root where the thickness of the buccal bone was <0.5 mm or where a buccal dehiscence‐type defect was present. Titanium implants were placed after a submerged healing period of 6 months and loaded after 20 ± 2 weeks (V8). Clinical parameters (e.g., bleeding on probing—BOP, probing pocket depth—PD, mucosal recession—MR, clinical attachment level—CAL) were recorded at V8 and after 26 ± 4 weeks (V9) of implant loading. Results At V9, all patients investigated revealed non‐significant changes in mean BOP (−19.23 ± 35.32%), PD (0.24 ± 0.49 mm), MR (0.0 ± 0.0 mm) and CAL (0.24 ± 0.49 mm) values, respectively. There was no significant correlation between the initial gain in ridge width and changes in BOP and PD values. Conclusions The surgical procedure was associated with stable peri‐implant tissues on the short‐term.

Objectives To assess the feasibility of using autogenous tooth roots (TR) for a lateral augmentation of deficient extraction sockets and two‐stage implant placement. Material and Methods A total of 15 patients were recruited to perform a simultaneous, lateral augmentation of deficient (i.e., thickness of the buccal bone < 0.5 mm or buccal dehiscence‐type defects) fresh extraction sockets using the respective non‐retainable but non‐infected teeth (n = 15). After 26 weeks of submerged healing, the primary endpoint was defined as the crestal ridge width (mm) (CW26) being sufficient to place an adequately dimensioned titanium implant at the respective sites. Results The surgical procedure could be accomplished in n = 14 patients. Soft tissue healing was uneventful in all patients. CW26 at visit 6 allowed for a successful implant placement in all patients (e.g., 14/14). Mean CW26 values amounted to 10.85 ± 2.71 mm (median: 8.5). The change (4.89 ± 2.29 mm) in CW compared to baseline was statistically significant (p < 0.001). Conclusions The usage of TR may represent a feasible approach for lateral augmentation of deficient extraction sockets and two‐stage implant placement.

BackgroundTo assess and compare the radiographic outcomes following lateral alveolar ridge augmentation using autogenous tooth roots (TR) and autogenous bone (AB) blocks.MethodsIn a total of 30 patients, lateral ridge augmentation was conducted in parallel groups using either (1) healthy autogenous tooth roots (e.g., retained wisdom or impacted teeth) (n = 15) or (2) cortical autogenous bone blocks harvested from the retromolar area. Cone-beam computed tomographic (CBCT) scans taken at 26 weeks of submerged healing were analyzed for the basal graft integration (i.e., contact between the graft and the host bone in %) (BI26) and the cross-sectional grafted area (mm2) (SA26).ResultsBoth groups revealed a comparable clinical width of the alveolar ridge at baseline (CWb). Mean BI26 and SA26 values amounted to 69.26 ± 26.01% (median 72.44) and 22.07 ± 12.98 mm2 (median 18.83) in the TR group and 79.67 ± 15.66% (median 78.85) and 12.42 ± 10.11 mm2 (median 11.36) in the AB group, respectively. Between-group differences in mean SA26 values were statistically significant (p = 0.031). Linear regression analysis failed to reveal any significant correlations between BI26 and CWb/SA26 values in either group.ConclusionsTR grafts may be associated with improved SA26 values following lateral alveolar ridge augmentation.Trial registrationDRKS00009586.

Lateral bone augmentation and staged implant placement are commonly used clinical procedures for the rehabilitation of noncontained alveolar ridge defects (Jepsen et al. 2019).Common treatment protocols employed a variety of materials applied as blocks or in particulate form (e.g., autogenous bone, xenografts, allografts, alloplasts, or combinations). These procedures were proven to be associated with a weighted mean bone width gain of 3.45 and ridge width of 6.36 mm (Naenni et al. 2019).A screwable equine-derived collagen-containing bone block (CXBB) was previously introduced as another potential alternative for lateral ridge augmentation. Its osteoconductive properties and timely remodeling were histologically demonstrated in various

Objectives To assess the long-term clinical outcomes following lateral alveolar ridge augmentation using a collagenated xenogeneic bone block (CXBB) and staged implant placement. Material and methods A total of n = 9 patients (9 implants) were available for the analysis. Each subject had received lateral ridge augmentation using a size-adapted rigidly fixed CXBB and contour augmentation at single-tooth gaps. Implant placement was performed after 24 weeks of submerged healing. Clinical parameters (e.g., bleeding on probing (BOP), probing pocket depth (PD), mucosal recession (MR)) were recorded at 16 to 20 weeks after the cementation of the crown (baseline) and scheduled for 0.5 (visit 1 (V1)), 1.5 (V2), 2.5 (V3), 3.5 (V4), and 4.5 (V5) years after implant loading. Results Changes in clinical parameters commonly remained low throughout the entire observation period. Significant changes to baseline were merely noted for mean BOP scores at V4 (19.14 ± 17.75%; n = 7; P = 0.029) and mean PD scores at V2 (0.78 ± 0.98 mm; n = 9; P = 0.044) and V3 (1.33 ± 1.05 mm; n = 9; P = 0.009), respectively. Conclusion CXBB was associated with high clinical implant success and survival rates on the long-term.

The present study conclude that the elderly patients of 60 years of age or more with moderate sensorineural hearing loss could catch up their normal hearing peers in their communication skills within six months only if they prescribed and used proper hearing aids.
