INTRODUCTION: When prepping for navigation surgery, a reference frame must be fixed to the patient's head with a Mayfield clamp, bone anchor, headset, or headband. Fixation of the clamp or bone anchor with a screw or head pins is invasive, whereas use of a headband or headset is noninvasive. However, during orbital surgery for blowout fractures or orbital tumors, surgeons or instruments can interfere between the reference frame and the optical tracking navigation system, even if using noninvasive fixation...

PURPOSE: To compare peri-implant bone and soft-tissue levels of immediate non-occlusally loaded versus non-submerged early loaded implants in partially edentulous patients 10 years after loading. MATERIALS AND METHODS: Fifty-two patients were randomised in five Italian private practices: 25 in the immediately loaded group and 27 in the early loaded group. To be immediately loaded, single implants had to be inserted with a torque of at least 30 Ncm, and splinted implants with a torque of at least 20 Ncm...

OBJECTIVE: Developments in digital technology have permitted researchers to study mandibular movements. Here, the accuracy of a real-time, computerized, binocular, three-dimensional (3D) trajectory-tracking device for recording functional mandibular movements was evaluated. METHODS: An occlusal splint without the occlusal region was created based on a plaster cast of the lower dentition. The splint was rigidly connected with a target on its labial side and seated on the cast...

PURPOSE: The aims of this study were to develop a device for in vivo measurement of three-dimensional (3D) loads on implants and to investigate the effects of implant configuration on the load distribution under a three-unit fixed partial denture (FPD). MATERIALS AND METHODS: A 67-year-old female patient with three implants (in the mandibular left second premolar, first molar, and second molar regions) was recruited. Four implant configurations for a three-unit FPD depending on the number and position of the implants were considered in this study...

Here, the author presents a case of bruxism-induced otalgia in a 29-year-old female patient. The pain was sharp and penetrating in character. It was usually worse in the morning and frequently radiated to the right temporal area. She had received unsuccessful medical treatments for migraine headache. The otoendoscopic examination revealed a normal tympanic membrane. A thorough inspection of her teeth revealed excessive wear on the incisal edges, and the cause of her otalgia was identified as bruxism-related temporomandibular joint disorder...

BACKGROUND: Granuloma annulare is a benign, inflammatory skin disorder with no distinct aetiology or widely accepted pathogenic process. CASE DESCRIPTION AND METHODS: We report a case of a 71-year old female with a 4-year history of an erythematous annulopapular lesion to the lateral aspect of her right forearm from a pressure pleat ridge in a high-density polyethylene plastic elbow orthosis to immobilise a prior radial head fracture. Morphological and histopathological assessment was consistent for granuloma annulare...

This article reports the orthodontic treatment of a 20-year-old patient with dental crowding and temporomandibular joint disorders (TMDs). The patient presented moderate anterior crowding with a Class I molar relationship and masticatory disturbance in the mandibular position induced by previous splint therapy. Orthodontic treatment with multi-bracket appliance was initiated to correct the anterior crowding in both dental arches, after the extraction of first premolars and third molars, and also to maintain the splint-induced position of the condyles...

PURPOSE OF REVIEW: To describe the development and refinement of the computer-assisted planning and execution (CAPE) system for use in face-jaw-teeth transplants (FJTTs). RECENT FINDINGS: Although successful, some maxillofacial transplants result in suboptimal hybrid occlusion and may require subsequent surgical orthognathic revisions. Unfortunately, the use of traditional dental casts and splints pose several compromising shortcomings in the context of FJTT and hybrid occlusion...

Objectives: Hereditary hemorrhagic telangiectasia (HHT) is characterized by the presence of vascular malformations with an absence of capillaries between arteries and veins. One major manifestation site is the nasal mucous membrane where recurrent nosebleeds occur. Our clinical strategy to treat patients with HHT has the aim to reduce nasal bleeding long-term with minimal local and general side effects. Methods: We describe staged diagnosis and therapy including individual medical treatments of 97 patients with HHT...

Accurate repositioning of the maxillary and mandibular segment is essential to improve esthetics and function in orthognathic surgery. With the improvement of three-dimensional imaging technology and computer-aided design and manufacturing techniques, various computer-aided design and manufacturing templates have been developed as alternatives to the traditional error-prone and time-consuming intermediate splint. However, the majority of previously developed templates still use an intermediate splint or the structures connected to occlusal surface and transferred the preoperative virtual plan to the real operation field indirectly...

Conventional model surgery planning for bimaxillary orthognathic surgery can be laborious, time-consuming and may contain potential errors; hence three-dimensional (3D) virtual orthognathic planning has been proven to be an efficient, reliable, and cost-effective alternative. In this report, the 3D planning is described for a patient presenting with a Class III incisor relationship on a Skeletal III base with pan facial asymmetry complicated by reverse overjet and anterior open bite. A combined scan data of direct cone beam computer tomography and indirect dental scan were used in the planning...

INTRODUCTION: The frequency of mandible fractures is relatively less in children compared with adults, but their treatment is significantly more challenging due to the concerns regarding mandible growth and the developing dentition. The authors have introduced a new way of closed reduction by using external nasal splints. METHODS: In 3 patients aged between 4 and 6-year old with parasymphyseal and body fractures of mandible, fractures were reduced under general anesthesia and thermoplastic nasal splints were directly formed and trimmed to fit the lingual surface of mandible...

Dental erosion is a global oral health problem that can lead to significant functional and esthetic impairments of the affected patients. Treatment of severe cases with augmented loss of the vertical dimension of occlusion (VDO) represents a challenge for both the dental team and the patient. CAD/CAM technology was used in the presented case to analyze the interocclusal space. Based on a virtual wax-up of the final restorations, CAD/CAM-fabricated preparation splints served as a guide and ensured a most minimally invasive preparation design...

INTRODUCTION: Management of mandibular condylar fractures is difficult in children with their inherently dynamic and unstable deciduous and mixed dentitions. We present a variation of the conservative fixed orthodontic approach that was used as an adjunct to aid in the reduction of a bilateral condylar fracture in a pediatric patient. METHODS: A boy, aged 10 years 9 months, came with clinical signs and symptoms of mandibular fracture after being involved in a motor vehicle accident...

This study aimed to evaluate an innovative workflow for maxillofacial fracture surgery planning and surgical splint designing. The maxillofacial multislice computerized tomography (MSCT) data and dental cone beam computerized tomography (CBCT) data both were obtained from 40 normal adults and 58 adults who suffered fractures. The each part of the CBCT dentition image was registered into MSCT image by the use of the iterative closest point algorithm. Volume evaluation of the virtual splints that were designed by the registered MSCT images and MSCT images of the same object was performed...
