BACKGROUND: To avoid cortical compression, several implant systems have included in the protocol dedicated drills aimed at widening the cortical region of osteotomy. However, the manual execution of this operation does not guarantee the necessary precision. Hence, the present study aimed to determine the optimal size of the recipient site at the level of the alveolar crest in relation to the size of the coronal region of the implant to achieve the best healing result. MATERIALS AND METHODS: Blades of different diameters were incorporated into the coronal part of the implant to prepare the cortical region of the mandibular alveolar bone crest in different dimensions in relation to the collar of the implant...

BACKGROUND: The surgical removal of impacted third molars is usually carried out by an oral/maxillofacial surgeon. Two specific risks of surgical removal of impacted third molars are oroantral communication (OAC) when extracting ​​upper third molars and hypesthesia of the inferior alveolar nerve (IAN) ​​when extracting lower third molars. The aim of this study is to determine the distribution of complications in deeply impacted third molar surgery, to identify specific risk factors influencing the most common perioperative (OAC, IAN hypesthesia) and to compare these results with other studies...

PURPOSE: Tori and exostoses are considered risk factors for the development of medication-related osteonecrosis of the jaw (MRONJ). The aims of this study were to present the prevalence of MRONJ located at tori in the Copenhagen ONJ Cohort, evaluate the surgical treatment of MRONJ located at tori and explore trauma to tori as an additional risk factor in patients on antiresorptive medication. METHODS: Data from a consecutive series of 506 patients with MRONJ (Copenhagen ONJ Cohort) were reviewed for the presence of tori and MRONJ located at tori...

We describe a case of mandibular gingival carcinoma with hypercalcaemia and leukocytosis caused by tumour-derived parathyroid hormone-related protein (PTHrP) and granulocyte colony-stimulating factor (G-CSF). A 54-year-old man presented to our Department of Oral and Maxillofacial Surgery with a chief complaint of a left-sided mandibular gingival ulcer. A 42 mm × 20 mm sized ulcer was found on the left lower molar gingiva. Squamous cell carcinoma was pathologically diagnosed. The patient underwent a hemimandibulectomy, left-sided radical neck dissection, plate reconstruction, pectoralis major musculocutaneous flap reconstruction, and tracheostomy under general anaesthesia...

For less fit patients, total reconstruction of the mandible (TRM) is an elucidated alternative for severe maxillofacial defects. This study aimed to comprehensively review and analyze the existing evidence, irrespective of the underlying pathologies, to provide a consolidated overview of the current state of TRM. An electronic search was performed on PubMed, Embase, Scopus, and Google Scholar to identify studies reporting TRM without restrictions on patient age, type of pathology underlying the mandibular defect, and study type...

PURPOSE: The aim was to assess skeletal stability after maxillary advancement using either distraction osteogenesis (DO) or conventional Le Fort I osteotomy (CO) in patients with cleft lip and palate (CLP) or cleft palate (CP) utilising a new superimposition-based cephalometric method. METHOD: This retrospective study included patients who were treated with DO (N = 12) or CO (N = 9). Sagittal and vertical changes after surgery, and skeletal stability at 18 months post-operatively were assessed with superimposition-based cephalometry, comparing lateral cephalograms performed pre-operatively (T0), post-operatively after CO or immediately after completed distraction in DO (T1), and at 18 months of follow-up (T2)...

OBJECTIVES: This study aims to provide insights into the developmental characteristics of the upper lateral incisor in individuals with unilateral clefts. MATERIALS AND METHODS: Panoramic radiographs of a consistent group of Caucasian children taken over time (ages 6, 9, and 12) were extensively reviewed. The study assessed the distribution pattern, eruption path, tooth development, and crown size of the upper lateral incisor within the cleft region. RESULTS: The most commonly observed distribution pattern was the lateral incisor located distal to the cleft, accounting for 49...

Noonan syndrome (NS) is a phenotypically variable inherited multi-system disorder. Maxillofacial findings can be diagnostic, especially in the evaluation of discrete facial dysmorphia. Diagnostic landmark findings of therapeutic relevance for the jaws such as central giant cell granuloma (CGCG) are rare in NS. However, recent molecular genetic studies indicate that these rare, benign lesions are neoplasms and more common in specific syndromes grouped under the umbrella term RASopathies. A specialist surgical diagnosis can be helpful in identifying the underlying disease...

PURPOSE: Jaw-stretching devices, including the Amplification, Resistance, and Kinetics of the Jaw (ARK-JSD), are an effective option for treating trismus after head and neck cancer (HNC) treatment. The force, however, that is applied to the patient's jaw is unknown. METHODS: Ten ARK-JSD devices were constructed for each of the levels of resistance (total of 30 samples). Each sample was tested using a Universal Testing Machine (UTM). RESULTS: The easy, medium, and hard ARK-JSD had a mean maximum force of 12...

OBJECTIVES: Hospitals in many European countries have implemented Additive Manufacturing (AM) technology for multiple Oral and Maxillofacial Surgery (OMFS) applications. Although the technology is widely implemented, surgeons also play a crucial role in whether a hospital will adopt the technology for surgical procedures. The study has two objectives: (1) to investigate how hospital type (university or non-university hospital) influences surgeons' views on AM, and (2) to explore how previous experience with AM (AM experience or not) influences surgeons' views on AM...

Condylar agenesis is a rare case involving developmental disturbances related to growth of mandible, facial aesthetics, dentition development, muscle deformation, and occlusal problems. As such, this is a rare condition, and there is no internationally accepted protocol for the same. Underdevelopment or defective formation of condyle may be congenital or acquired. Condylar agenesis is congenital non formation of condyle, while hypoplasia is poor development. We report a case of bilateral condylar agenesis in a 30-year-old female patient...

OBJECTIVE: This study aimed to verify whether tooth extraction before the administration of bone-modifying agents (BMA) was effective in preventing the onset of medication-related osteonecrosis of the jaw (MRONJ). MATERIALS AND METHODS: This retrospective study included patients with a history of receiving BMA for cancer treatment. The patients were classified into three groups based on the timing of tooth extraction: no tooth extraction before the onset of MRONJ, tooth extraction before the administration of BMA, and tooth extraction after the administration of BMA...

PURPOSE: To clarify reasons for infections, surgical techniques, and occurrence of postoperative surgical site complications in infected mandibular fractures. METHODS: Patients with clinically infected mandibular fracture of the dentate part without preceding surgery were studied retrospectively. Clinical infection was defined to occur if pus, abscess, or a fistula in the fracture area was present.

BACKGROUND: Healing of critical-size defects is a well-known problem that has been challenged in several studies. The aim of the experiment was to evaluate bone formation and osseointegration of implants installed in critical defects of the mandibular body simultaneously grafted with Bio-Oss® or Cerabone®. MATERIAL AND METHODS: Defects, 10 mm wide and 3 mm deep, were prepared at both lateral aspects of the mandible in 12 rabbits. One implant was installed in the center of the defect, and bovine xenografts produced either at low (Bio-Oss®; Low-T) or high (Cerabone®; High-T) temperatures were used to fill the defects...

PURPOSE: Although functional and esthetic results after the use of a scapular tip free flap (STFF) in head and neck reconstruction, and the related donor-site morbidity, have been extensively described, data regarding acute postoperative donor-site pain management are lacking. Purpose of this study is to explore the use of mini-catheters to administer local anesthetics for donor-site pain management after reconstruction using STFF. METHODS: Patients who underwent head and neck reconstruction using a STFF were prospectively enrolled and, through a perineural catheter placed in the donor site during the surgical procedure, a bolus of chirochaine was injected before the patient regained consciousness and at 8, 16, and 24 h postoperatively...
