Evaluating success of autotransplantation of embedded/impacted third molars harvested using piezosurgery: a pilot study.

OBJECTIVE: To evaluate the success of autogenous transplantation of embedded/impacted third molars harvested using piezosurgery. MATERIALS AND METHODS: This prospective pilot study enrolled 20 healthy patients with non-restorable first/second molars and a caries-free retrievable embedded/impacted third molar. Piezosurgery was used for removing inter-radicular bone at the recipient socket as well as for bone removal around the donor teeth. RESULTS: After an average follow-up of 16.4 months (SD = 1.9), 18 cases were successful with formation of periodontal ligament around the teeth. One tooth

The effect of Emdogain gel on periodontal healing in replanted monkeys' teeth.

OBJECTIVE: We sought to histologically evaluate the effect of Emdogain gel on periodontal healing in monkeys' teeth undergoing delayed replantation. Study design Mature monkey teeth simulating avulsion were endodontically treated before extraction. Negative control teeth (group N = 10 roots) underwent immediate replantation, whereas the rest were bench-dried for 1 hour and treated in one of the following ways before replantation: the positive control teeth (group P = 12 roots) had no further treatment; group C teeth (4 roots) had the periodontal ligament removed; group D teeth (10 roots) were

Intentional replantation and dental autotransplantation of mandibular posterior teeth: Two case reports.

BACKGROUND: Intentional replantation and dental autotransplantation are 2 similar techniques both involving atraumatic tooth extraction, visualization of the root, and replantation. They are considered as the last resort for unsalvageable teeth. The author aims to describe 2 mandibular posterior teeth with serious periapical lesions which are resolved by intentional replantation and dental autotransplantation, respectively. CASE SUMMARY: In case 1, a 45-year-old male patient received root canal treatment because of a cracked mandible right first molar with periapical lesions. An endodontic fi

Clinical evaluation of forceps eruption: reestablishing biologic width and restoring no restorable teeth.

INTRODUCTION: Complicated crown- root fractures, extended caries and iatrogenic destruction often result in insufficient sound tooth structures and compromise the biologic width. Two common options for re-establishing flap with osseous surgery. Although some advantages are related to these two options, but coronal movement of gingival and alveolar bone in orthodontic extrusion, esthetic problem and inconsistent topography between the involved tooth and the adjacent teeth following osseous surgery are the involved tooth and the adjacent teeth following osseous surgery are the major disadvantage

BACKGROUND: The present study examined how bone improvement techniques, particularly the use of lovastatin with ridge preservation strategie … mg of lovastatin, while group B received a synthetic bone graft alone. The graft was placed in the tooth socket and covered with a collagen cone for support. After nine months, a histomorphometric analysis assessed horizontal changes, using a clipper in the area compared to pre-treatment clinical measurements (P≤0.05). RESULTS: The study examined 40 areas an …

Odontogenic Maxillary Sinusitis With Sequestrum-Like Bone Formation Mimicking Fungal Sinusitis: A Case Report.

Calcified materials in an opacified maxillary sinus often suggest fungal sinusitis, particularly aspergillosis. However, odontogenic maxillary sinusitis may rarely be associated with a bone-like calcified mass, creating diagnostic difficulty. We report a case of chronic odontogenic maxillary sinusitis with sequestrum-like bone formation that mimicked fungal sinusitis. An 88-year-old man was referred for mobility and occlusal pain of the maxillary left first molar. He had no nasal obstruction, rhinorrhea, headache, facial pain, or history of maxillary sinus surgery. Intraoral examination showed

Enhanced Bone Regeneration Using Demineralized Dentin Matrix: A Comparative Study in Alveolar Bone Repair.

OBJECTIVES: Alveolar bone resorption following tooth extraction presents significant challenges for implant-supported rehabilitations. Demineralised dentin matrix (DDM) has emerged as a promising scaffold for bone tissue regeneration. This study evaluates the bone-regenerating potential of varying degrees of dentin demineralisation. MATERIALS AND METHODS: Thirty-two male white New Zealand rabbits underwent extraction of the left mandibular anterior tooth and were assigned to 4 groups: undemineralised dentin matrix (UDDM), partially demineralised dentin matrix (PDDM), completely demineralised

Alveolar Ridge Preservation Using a Composite Graft Plug: Clinical and Radiographic Outcomes From a Randomized Clinical Trial.

Various grafting materials have been used for alveolar ridge preservation with varying degrees of success in maintaining ridge dimensions. This study compared the clinical and radiographic outcomes of a composite graft plug containing bioactive, resorbable calcium apatite crystals embedded in a collagen matrix with those of a corticocancellous allograft. This randomized clinical trial included 24 participants requiring single-rooted tooth extractions. The participants were randomly assigned to 1 of 2 groups: composite plug or allograft. Clinical measurements of soft tissue thickness were obtai

Effectiveness of purple leaves (Graptophyllum pictum L. Griff) and hydroxyapatite as socket preservation biomaterials.

BACKGROUND: Tooth extraction without socket preservation will lead to reduction in the dimensions and volume of the alveolar bone. Bone defects resulting from tooth extraction not only hinder prosthetic reconstruction but also present aesthetic issues and complicating dental implant treatment. Purple leaves contains flavonoids, steroids, tannins, saponins,and non-toxic alkaloids. These compounds play roles as antimicrobials, immunomodulators, antioxidants, anti-inflammatories, analgesics. Hydroxyapatite has good biocompatibility, and can induce osteoblast differentiation. AIM: To investigate

Effect of nanocrystalline hydroxyapatite socket preservation on orthodontically induced inflammatory root resorption.

OBJECTIVE: Orthodontically induced inflammatory root resorption (OIIRR) is considered to be an important sequel associated with orthodontic tooth movement (OTM). OTM after Socket preservation enhances the periodontal condition before orthodontic space closure. The purpose of this study is to investigate the histologic effects of NanoBone®, a new highly nonsintered porous nano-crystalline hydroxyapatite bone on root resorption following OTM. MATERIALS AND METHODS: This experimental study was conducted on four male dogs. In each dog, four defects were created at the mesial aspects of the maxill

Interproximal Soft Tissue Height Changes After Unassisted Socket Healing vs Alveolar Ridge Preservation Therapy.

The primary aim of this study was to evaluate the efficacy of alveolar ridge preservation (ARP) therapy compared with unassisted socket healing (USH) in attenuating interproximal soft tissue atrophy. Adult patients who underwent maxillary single-tooth extraction with or without ARP therapy were included. Surface scans were obtained and CBCT was performed to digitally assess interproximal soft tissue height changes and measure facial bone thickness (FBT), respectively. Logistic regression models were conducted to investigate the individual effect of demographic and clinical variables. Ninety-si

Peri-implant tissue response following connective tissue and bone grafting in conjunction with immediate single-tooth replacement in the esthetic zone: a case series.

PURPOSE: This case series evaluated the peri-implant tissue response following extraction and immediate placement and restoration of an implant in conjunction with subepithelial connective tissue grafting (SCTG) and bone grafting in the esthetic zone. Implant success rates and the peri-implant tissue response were also reported. METHODS AND MATERIALS: Ten patients (four men, six women) with a mean age of 48 years (range, 35 to 70) underwent extraction and immediate tooth replacement with SCTG and were evaluated clinically and radiographically presurgically (T0), immediately after immediate to

Impact of Bone Particle Size on Alveolar Ridge Preservation in Periodontally Compromised Molar Extraction Sites.

INTRODUCTION AND AIMS: The clinical efficacy of alveolar ridge preservation (ARP) is well-documented in the literature. However, there is a lack of evidence regarding ARP in the posterior area and in periodontally compromised sites. There is no clinical decision-making guideline on the choice of bone substitute particle size for ARP in periodontally compromised molar sockets. This study aimed to compare the radiographic outcomes and implant feasibility of two deproteinized bovine bone mineral (DBBM) particle sizes for alveolar ridge preservation (ARP) in periodontally compromised molar extract

Efficacy of Injectable Bone Fillers for Alveolar Ridge Preservation: A Histomorphometrical Analysis.

AIM: To assess the efficacy of injectable bone fillers for alveolar ridge preservation (ARP). MATERIALS AND METHODS: The mandibular premolars (P2, P3, P4) were bilaterally assigned to ARP in a total of n = 9 beagle dogs. Each P was decapitated and hemisected under preservation of the mesial (i.e., devitalization and filling with calcium hydroxide) and removal of the distal root. The resulting 6 extraction sockets were randomly allocated to a total of four injectable test materials (i.e., bovine bone particles + porcine collagen, lyophilized materials reconstituted with either blood or saline

Immediate Augmentation of Compromised Extraction Sockets in Chronic Periodontitis Patients: 1-Year Results of a Case Series on Volumetric and Histologic Response.

The present case series evaluated three-dimensional volumetric bone tissue changes and new bone formation in severely resorbed extraction sockets augmented with Bio-Oss collagen and a covering collagen membrane in nine chronic periodontitis patients. Healing was by secondary intention. After 12 months of healing, the augmentation procedure appeared not only to compensate for bone remodeling but also appeared to repair a significant portion of the buccal wall. The mineralized tissue filled the 91.49% ± 6.77% of the maximum volume for regeneration. Overall, a mean of 49.6% new bone, 27.1% residu

Effects of experimental osteoporosis and low calcium intake on postextraction sockets of rats.

This study analysed the initial effects of the combination of oestrogen deficiency with a calcium-deficient diet on alveolar bone repair. Sixty-three 3-month-old female rats were either ovariectomized (OVX, n = 42) or sham-operated (SHAM, n = 21). Among the 42 ovariectomized rats, 21 received standard commercial food (OVX) and 21 received food with low calcium content (ESP). The mandibular first molars were extracted bilaterally 15 days after ovariectomy or sham surgery. The rats were weighed and killed at 7, 21 and 45 days after tooth extraction. The results were evaluated by descriptive micr

Autogenous free tooth transplantation with a two-stage operation technique.

If tooth transplantation is to succeed, it is crucial to preserve the vitality of the cells on the root surface of the tooth transplant. Insufficient postoperative nutrition to the cells on the root surface of the tooth transplant was thought to contribute to their devitalization of these cells. Impaired nutrition may be a result of poor contact between the recipient bed and the root surface of the transplanted tooth, and development of an interposed blood clot. To improve postoperative nutrition to the root surface cells, teeth were transplanted to the recipient beds in which the tissues were

Long-term stability of soft tissues following alveolar ridge preservation: 10-year results of a prospective study around nonsubmerged implants.

The purpose of this study was to evaluate the long-term clinical outcomes around implants placed in sites previously augmented with demineralized bovine bone mineral with 10% collagen (Bio-Oss Collagen, Geistlich). In this prospective study, 36 consecutive, healthy patients, in need of a single-tooth extraction (incisors, canines, and premolars) and implant replacement, were included. After tooth extraction, Bio-Oss Collagen was inserted in the socket and covered either with a double layer of collagen membrane (test) or with a few drops of a flowable polylactide polymer (control). Following a

Implant therapy and apical actinomycosis: case report.

Treatment of periapical actinomycosis includes extraction of the involved tooth; however, indications for and timing of implant therapy remain unclear. In this case report, we describe treatment of apical actinomycosis in a 63-year-old woman following tooth extraction. After monitoring the patient for 6 months, implant therapy was carried out and remained successful after 1 year follow-up.
