For restorations on teeth involving invasion of the supracrestal tissue attachment (biological width), as well as for lack of ferrule effect, crown lengthening is required for long-term periodontal health and success of the restoration. In the same fashion, site development is often necessary prior to implant placement in order to provide optimal peri-implant soft and hard tissue architecture conducive to future esthetics and function. Orthodontic extrusion, also known as forced eruption, has been developed and employed clinically to serve the purposes of increasing the clinical crown length, correcting the periodontal defect, and developing the implant site. In order to provide comprehensive guidance on the clinical usage of this technique and maximize the outcome for patients who receive the dental restoration, the currently available literatures were summarized and discussed in the current review. Compared to traditional crown lengthening surgery, forced eruption holds advantages of preserving supporting bone, providing improved esthetics, limiting the involvement of adjacent teeth, and decreasing the negative impact on crown-to-root ratio compared to the traditional resective approach. As a non-invasive and natural technique capable of increasing the available volume of bone and soft tissue, forced eruption is also an attractive and promising option for implant site development. Both fixed and removable appliances can be used to achieve the desired extrusion, but patient compliance is a primary limiting factor for the utilization of removable appliances. In summary, forced eruption is a valuable treatment adjunct for patients requiring crown lengthening or implant restorations. Nonetheless, comprehensive evaluation and treatment planning are required for appropriate case selection based upon the known indications and contraindications for each purpose; major contraindications include inflammation, ankylosis, hypercementosis, vertical root fracture, and root proximity. Further studies are necessary to elucidate the long-term stability of orthodontically extruded teeth and the supporting bone and soft tissue that followed them.

Molar–incisor pattern periodontitis (MIPP) is a severe form of periodontal disease characterized by rapid attachment loss and bone destruction affecting the molars and incisors. Formerly referred to as aggressive periodontitis, the terminology for this condition was revised after the 2017 workshop on the classification of periodontal and peri-implant diseases and conditions. Despite the modification in nomenclature, the treatment strategies for MIPP remain a critical area of investigation. The core principles of MIPP treatment involve controlling local and systemic risk factors, managing inflammation, and arresting disease progression. Traditional non-surgical periodontal therapy, including scaling and root planing, is commonly employed as an initial step together with the prescription of antibiotics. Surgical intervention may be necessary to address the severe attachment loss. Surgical techniques like resective and regenerative procedures can aid in achieving periodontal health and improving esthetic outcomes. This review article aims to provide an overview of the current understanding and advancements in the treatment modalities of MIPP. Through an extensive analysis of the existing literature, we discuss various modern therapeutic approaches that have been explored for managing this challenging periodontal condition.

Background: Over the past two decades, with the collaboration between periodontists and orthodontists, the concept of a surgically facilitated orthodontic therapy (SFOT) approach was developed, which not only provides acceleration in tooth movement as a result of a stimulated regional acceleratory phenomenon but also increases the alveolar bone volume for orthodontic tooth movement range by bone grafting. Despite the benefits, hard and soft tissue defects can sometimes be observed in patients post SFOT, especially among groups with thin periodontal phenotypes. Methods: In the current study, we compared the traditional SFOT with allograft only and the modified SFOT with allograft and collagen matrix to explore if the addition of a collagen matrix between the bone graft and periodontal flap could achieve soft tissue augmentation and reduce the prevalence of the complications of SFOT. Six patients were initially enrolled in the current study. Four patients showed up for the 1-week and 2-week post-operation evaluations. However, only one subject of each group agreed on periodontal evaluation by bone sounding and CBCT during the 6-month follow-up appointment. Results: Six months post SFOT, the patient with the modified SFOT presented with a larger amount of soft tissue thickening compared to the patient with traditional SFOT. However, the location of bone generation was different between groups, with the modified SFOT group presenting with bone generation more apically. In addition, patients with modified SFOT reported a more severe level of discomfort than patients with traditional SFOT. Conclusions: The modified SFOT may potentially improve soft tissue phenotype; however, further modifications are needed to reduce the patient’s discomfort level and to ensure that bone particles are contained more incisally.

Since the development of CBCT has been utilized in dentistry, the images of the CBCT can assist the surgeon to evaluate the anatomy carefully. Despite the value of radiology evaluation, implant procedures may require additional consideration rather than only evaluating the anatomical factors. The purpose of this study is to evaluate the predictability of using CBCT alone to plan for implant placement in edentulous patients digitally. CBCT images were analyzed by clinicians, measuring the maxillary and mandibular ridge heights and widths digitally of four predetermined implant sites in the maxillary and two selected implant sites in the mandibular arches of 91 patients planning for implant-supported overdenture. A total of 47 patients out of the 91 had completed implant placement on the edentulous ridge, contributing to 55 upper and/or lower arches (136 dental implants). Both predictabilities are low, implying that CBCT planning for implant placement on the edentulous ridge is not a good index and is insufficient to predict the surgical procedures as a solo method. The findings of this study indicate that digital planning by CBCT is insufficient to serve as an individual tool to predict implant procedures. Further information and evaluation must be considered for implant placement in the edentulous ridge.

Background: Autogenous particulate dentin has emerged as one of the promising biocompatible alternatives to traditional bone graft materials in alveolar ridge augmentation. Although its clinical success is documented, comprehensive studies combining histological and radiographic evaluations remain limited. This case report addresses this gap by detailing a novel approach using autogenous particulate dentin combined with cancellous allograft and a long‐lasting absorbable barrier membrane (lasso‐guided bone regeneration technique) for horizontal ridge augmentation. Methods and Results: A 49‐year‐old female presented with insufficient alveolar ridge width (Seibert Class I) at edentulous sites #12 and #14, necessitating bone augmentation before implant placement. The procedure involved a layered approach: Cancellous allograft (internal layer, faster remodeling) followed by autogenous particulate dentin (outer layer, slower remodeling). A bovine pericardium membrane was used to isolate the graft site and promote healing. Six months post‐surgery, cone‐beam computed tomography scans demonstrated significant alveolar ridge width gains of 4.64 mm at #12 and 4.21 mm at #14. Implants were successfully placed, and a bone core harvested at the 4‐month mark confirmed the slow remodeling rate of the dentin particles compared to the allograft. One year post‐restoration, the implants remain functional. Conclusion: This case report highlights the efficacy of the layered approach using autogenous particulate dentin, particularly for space maintenance. The slower remodeling rate of dentin suggests its suitability as an outer layer, enhancing long‐term stability. This innovative technique and material selection may represent a significant advancement in alveolar ridge augmentation procedures. Further studies are warranted to confirm these findings and determine optimal applications in the long term. Key points: The case demonstrates that a biologically driven layered grafting approach—placing cancellous allograft internally for faster remodeling and autogenous particulate dentin externally for slower turnover and superior space maintenance—is an option to perform horizontal ridge augmentation by mimicking natural bone architecture. Histologic findings highlight that dentin particles remodel very slowly yet remain well integrated within the grafted site without complications, contributing to stability while allowing substantial formation of vital bone. This confirms that autogenous dentin serves as a reliable, long‐lasting scaffold that supports new bone formation. However, long‐term evaluation may still be necessary. The use of a long‐lasting absorbable pericardium membrane stabilized with the lasso GBR technique ensures membrane security, space preservation, and tension‐free primary closure—factors that collectively promote predictable healing and successful guided bone regeneration consistent with biology. Plain language summary: This case report presents a new approach for rebuilding bone in the jaw to allow for dental implant placement. A 49‐year‐old woman had insufficient bone width in the upper jaw, which made implant treatment impossible without bone augmentation. To solve this, the treatment combined two materials: donated human bone on the inside, which remodels quickly, and the patient's own tooth material, ground into small particles, on the outside, which remodels more slowly and helps maintain space. A protective membrane was used to stabilize the graft and promote healing. After 6 months, 3D scans showed a significant increase in bone width, allowing implants to be placed successfully. A small bone sample confirmed the slow remodeling of the tooth particles compared with the donated bone. One year after the final restoration, the implants remained functional and stable. This technique suggests that using a patient's own tooth material, combined with other grafting materials, may provide a safe and effective alternative for jawbone reconstruction. It may also reduce the need for animal‐derived products while improving long‐term stability for implant treatments.
