The aim of this study was to present our SARPE technique and to report about our experience. MATERIEL AND METHOD: Medical records of all class III patients who underwent SARPE in our department from 2010 to 2015 and for whom a follow-up of at least 1year was available, were included in a retrospective study. The technique consisted, after short orthodontic preparation allowing for divergence of the upper central incisors, in a complete Le Fort I os

Bone stability after regenerative peri-implantitis treatment: A 10-year follow-up case study.

BACKGROUND: Peri-implantitis poses a significant challenge to implant longevity, leading to progressive bone loss and potential implant failure. While reconstructive surgery has been proven effective in regenerating peri-implant tissues, the long-term stability of the regenerated tissues and the impact of supportive peri-implant care (SPIC) on bone levels remains underexplored. This case study presents a 10-year follow-up of a patient treated with reconstructive surgery for peri-implantitis and enrolled in a structured maintenance program. METHODS: A 68-year-old male with a failing implant in

The in vitro effect of pulpal pressure and luting agent on tensile bond strength of complete cast crowns.

STATEMENT OF PROBLEM: The degree to which pulpal pressure may affect bond strength of complete cast crowns is unknown. PURPOSE: The aim of this in vitro study was to evaluate the effect of simulated pulpal pressure on the tensile bond strength of complete cast crowns luted with 2 different cements. MATERIAL AND METHODS: Forty-eight human mandibular canine teeth were cleaned and stored in saline solution. The crowns were prepared by 1 investigator, and standardization of the preparation was accomplished by fixing a dental handpiece in a parallelometer. Uniform grooves, 0.5 mm in depth, were p

Endoscopically assisted intraoral modified Le Fort II type midfacial advancement using piezoelectric surgery and an intraoperative RED system.

PURPOSE: The Le Fort II midfacial advancement appears to be an effective surgical method for the treatment of severe midfacial-nose hypoplasia with a skeletal class III malocclusion, which is usually combined with syndromic midfacial anomalies. However, the conventional surgical method requires the coronal approach, including a coronal incision, together with other surgical approaches, such as an intraoral incision. Therefore, surgeons often hesitate to propose this type of osteotomy, even for patients who develop severe nonsyndromic midfacial-nose hypoplasia. This report presents a new surgic

Qualitative radiographic characteristics of MRONJ-affected bone in oral and parenteral drug administration: comparison of panoramic radiography and cone-beam CT.

BACKGROUND: Our aim was to compare the capacity of panoramic radiography (PR) and cone-beam computed tomography (CBCT) first for the detection of bone affected by medication-related osteonecrosis of the jaw (MRONJ) using qualitative radiographic parameters; and second for the evaluation of the relationship between drug administration route and associated bone changes. METHODS: PR and CBCT images of 24 MRONJ patients using oral or intravenous (IV) bisphosphonates were scored for the detection of osteolysis, osteosclerosis, lamina dura thickening, periodontal ligament widening, persistent extrac

Fibula flap versus soft tissue flap with reconstruction plate for mandibular stage 3 medication-related osteonecrosis of the jaw: a retrospective cohort study.

The facial skeleton in patients with osteoporosis: a field for disease signs and treatment complications.

Osteoporosis affects all bones, including those of the facial skeleton. To date the facial bones have not drawn much attention due to the minimal probability of morbid fractures. Hearing and dentition loss due to osteoporosis has been reported. New research findings suggest that radiologic examination of the facial skeleton can be a cost-effective adjunct to complement the early diagnosis and the follow up of osteoporosis patients. Bone-mass preservation treatments have been associated with osteomyelitis of the jawbones, a condition commonly described as osteonecrosis of the jaws (ONJ). The fa

Связанный с лекарственными препаратами остеонекроз челюсти (MRONJ) является редким побочным эффектом некоторых лекарственных средств, главным образом тех, которые используются при лечении конкретных раковых заболеваний и при первоначальном лечении ненеопластических заболеваний. Первые случаи остеонекроза челюсти были зарегистрированы в ходе 2 десятилетия назад у пациентов, употребляющих бисфофонаты (БП). После идентификации номенклатура перешла от остеонекроза челюсти (BRONJ) к MRONJ, поскольку другие лекарства могут вызвать такую же реакцию. Инвазивные стоматологические услуги, такие, как экс

Platelet-rich plasma (PRP) in dental and oral surgery: from the wound healing to bone regeneration.

Platelet-rich plasma (PRP) is a new approach to tissue regeneration and it is becoming a valuable adjunct to promote healing in many procedures in dental and oral surgery, especially in aging patients. PRP derives from the centrifugation of the patient's own blood and it contains growth factors that influence wound healing, thereby playing an important role in tissue repairing mechanisms. The use of PRP in surgical practice could have beneficial outcomes, reducing bleeding and enhancing soft tissue healing and bone regeneration. Studies conducted on humans have yielded promising results regard

Tips and Tricks and Clinical Outcome of Cryopreserved Human Amniotic Membrane Application for the Management of Medication-Related Osteonecrosis of the Jaw (MRONJ): A Pilot Study.

Medication-related osteonecrosis of the jaw (MRONJ) is a complication of certain pharmacological treatments such as bisphosphonates, denosumab, and angiogenesis inhibitors. There are currently no guidelines on its management, particularly in advanced stages. The human amniotic membrane (hAM) has low immunogenicity and exerts anti-inflammatory, antifibrotic, antimicrobial, antiviral, and analgesic effects. It is a source of stem cells and growth factors promoting tissue regeneration. hAM acts as an anatomical barrier with suitable mechanical properties (permeability, stability, elasticity, flex

Chinese expert consensus on the diagnosis and clinical management of medication-related osteonecrosis of the jaw.

Medication-related osteonecrosis of the jaw (MRONJ) is a side effect that occurs after treatment for systemic diseases. However, most institutions currently rely on empirical methods to make diagnosis and treatment plans, and there is a lack of consensus or guidelines for the classification, staging and treatment of MRONJ in China. To address this gap and improve prognosis, an expert panel representing 11 renowned domestic medical colleges and affiliated hospitals in China was convened. The panel made a comprehensive literature review of previous treatment experiences and research findings to

A 5-year retrospective cohort study of denosumab induced medication related osteonecrosis of the jaw in osteoporosis patients.

Denosumab has been suggested as a first-line therapy for osteoporotic patients. However, a standardized protocol for the prevention of denosumab induced medication-related osteonecrosis of the jaw (MRONJ) has not yet been established. The purpose of this study was to report denosumab induced MRONJ cases, and investigate the factors affecting the occurrence of MRONJ in patients who underwent denosumab and invasive dental treatment (especially tooth extraction) between October 2016 and March 2020. Four of the 98 patients developed MRONJ before and after tooth extraction. The participants were di

Bisphosphonate-Related Osteonecrosis of the Jaw (BRONJ) therapy. A critical review.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is an area of uncovered bone in the maxillo-facial region that did not heal within 8 weeks after identification by health care provider, in a patient who was receiving or had been exposed to Bisphosphonate Therapy (BPT) without previous radiation therapy to the craniofacial region. Low-grade risk of ONJ is connected with oral BPT used in the treatment of osteopenia, osteoporosis and Paget's disease (from 0.01% to 0.04%) while higher-grade risk is associated with intravenous (IV) administration in the treatment of multiple myeloma and bone

Мандибулярная плазмоцитома как первоначальное проявление несекретарской множественной миеломы: Редкая диагностика.

Плазменные клеточные новообразования, связанные с челюстями, редки, при этом мантибулярное участие представляет собой редкое первоначальное проявление системной множественной миеломы (ММ). Их неспециальная клиническая и радиография часто имитирует более распространенные одонтогенные и подстрекательские условия, что затрудняет раннюю диагностику. Мы сообщаем о случае с 81-летним мужчиной, который испытывал боль и опухоль на левой задней челюсти в течение двух месяцев. Клиническое обследование выявило диффузный отек левого челюсти и угла.
