Abstract Background This study investigated the prevalence of labial bone perforation (LBP) related to the associated anatomic factors in anterior mandibular region using a virtual immediate implant placement procedure. Methods Series qualified CBCT images of 149 participants (894 teeth) were selected to analyze the assigned anatomical parameters, including concavity depth, concavity angle, torque, and deep bone thickness. Four classes of crestal and radicular dentoalveolar bone phenotypes (CRDAPs) of mandibular anterior teeth were categorized according to the thickness of dentoalveolar bone at both crestal and radicular zones. Data were adjusted for categorical (gender and CRDAP) and continuous (age, cavity angle, cavity depth, and deep bone thickness) variables using a multivariable logistic regression analysis with generalized estimating equation method. Results The overall probability of LBP after virtual implant placement was 21.6%. There is statistically significant higher prevalence of LBP at canine (28.5%) and CRDAP class II (29.2%) regions (p < 0.001). After adjusting confounding variables, CRDAP class II and class IV regions are more likely to have LBP when compared with CRDAP class I (control) regions (p < 0.01). The risk of LBP at canine site is 6.31 times more likely than at the central incisor (control) (p < 0.01). Conclusions Using a virtual immediate implant placement technique, the prevalence of LBP is significantly higher at the mandibular canine site and thin radicular dentoalveolar phenotype in the anterior mandibular region.

Objective: Reporting the application of SBA procedure with titanium mesh as an alternative solution for immediate implant placement in socket with dentoalveolar trauma-induced buccal bone defect.Methods: An 18-year-old female patient visited our department, with a history dentoalveolar trauma and a loss of  tooth 21. Clinical examination during the implant placement procedure exposed  a socket with buccal bone defect. SBA with autogenous chin bone graft combined with DFDBA allograft and stabilized with titanium mesh (Ti-Mesh) for buccal defect on which flap reposition was done with tension free primary closure.Results: Ti-Mesh was removed after 3 months which no sign of inflamation appeared, implant was in a stable condition and new bone formation was observed. Subsequently, healing abutment was placed. A one-year observation suggested a good clinical retention with no luxation observed, along with decent functional and esthetic results. CBCT evaluation showed buccal bone thickness preserved.Conclusion: Sandwich bone augmentation with stabilized titanium mesh provides a satisfying result in treating horizontal buccal bone defect.

Abstract Background: To assess the root angle characteristics of maxillary incisors, and to analyze the relationship between the root angle and other implant-related anatomical indices to use the sagittal root angle as an index for immediate implant evaluation and design. Methods: A random sample consisting of 400 cone-beam computed tomography (CBCT) images and 65 maxillary plaster models were selected for the present study. CBCT and stereolithography (STL) scan images were imported as DICOM files into coDiagnostiX software for matching the hard and soft tissue. The angle between the long axis of the anterior tooth and the corresponding alveolar bone and implant-related hard and soft tissue indices were measured in the sagittal section. Descriptive statistics, frequency analysis, multi-level comparisons, and correlation analyses were performed. Results: The average sagittal root angles were 15° at the central incisor and 19° at the lateral incisor. The root angle in males was significantly larger than that in females, and increased with age. The largest angle, 22.35º, was found in the lateral incisors of the oldest (> 50 years old) male group. The root angle was found to correlate with coronal buccal bone thickness, coronal palatal bone thickness, apical buccal bone thickness, palatal bone thickness, and the below apex bone thickness. Conclusions: The sagittal root angle could reflect the distribution of other implant-related anatomical indices, which may provide additional reference for the evaluation of immediate implant placement.

AbstractEdentulism is most often the result of repeated tooth extraction from combined pathological process and/or dental trauma. Dental implants have emerged to be a highly successful and predictable treatment modality for replacement of missing teeth. Dental implants are the devices that are surgically inserted into the jaw bone to support a single prosthetic tooth and serve as abutments or as cosmetic replacements for missing teeth. Timing of implant placement following tooth removal may be important and this concept has challenged the original treatment protocol. This article aims to present two case reports of immediate placement of implant.
