A SIMPLE INSTRUMENT TO DEFINE THE FRANKFURT HORIZONTAL PLANE FOR SOFT-TISSUE MEASUREMENTS OF THE FACE

Purpose: The purpose of the study was to compare measurements of maxillary occlusal cant obtained through facebow transfer and through lateral cephalogram. Method: 40 subjects were included in this study according to inclusion and exclusion criteria and divided into two groups: dentulous and edentulous. For edentulous subjects, all the steps of complete denture fabrication were carried out and finished dentures were delivered. Alginate impressions were now made for all the subjects (with complete denture worn in edentulous cases) for both upper and lower arches. The study was conducted in two parts. Facebow transfer was done next and casts were mounted. In first part of the study, sagittal inclination was measured after facebow transfer. After mounting of the casts, four points were marked to measure the inclination of the occlusal plane. In second part, cephalometric evaluation of occlusal plane and Frankfurt horizontal plane was carried out. Angle between Frankfurt horizontal plane and the occlusal plane was maxillary occlusal cant. which was evaluated by tracing. Paired t test was used to compare mean facebow values and lateral ceph values in edentulous subjects. Intergroup comparison between lateral ceph and mean facebow values between dentulous and edentulous subjects was evaluated using independent t test. Results: Facebow measurements gave comparatively higher values in both dentulous and edentulous patients and are subjected to less variation as compared to the lateral cephalogram values p<0.0001. Conclusion: The occlusal plane angle of lateral cephalogram was found to be significantly different from angle obtained through facebow transfer.

Abstract Objective The main purpose of this article was to determine the correlation of bite force in maximal intercuspal position (MIP) among patient’s perceptions, clinician subjective interpretation, and T-Scan III system. Materials and Methods Forty-three dental students at Naresuan University (Phitsanulok, Thailand) participated in the study. Subjects were positioned by Frankfurt horizontal plane paralleled to the horizontal plane and asked to bilaterally clenched in MIP. Patient’s perception was evaluated by asking which side of the jaw had heavier bite force (right, left, or equally on both sides). Then, the clinician subjective interpretation was assessed using traditional occlusal indicators. Furthermore, patient’s bite force was analyzed using T-Scan III. Statistical Analysis Cohen’s weighted kappa test was used to evaluate the correlation of bite force. Results The best correlation between patient’s perception and T-Scan III was at the ± 7.5% cutoff range with 15 subject agreements. While the best correlation between clinician subjective interpretation and T-Scan III was at ± 5.0% cutoff range with 23 subject agreements. Cohen’s weighted kappa indicated slight agreement between T-Scan III and patient’s perception and fair agreement between T-Scan III and clinician. Conclusions Clinician subjective interpretation is more clinically reliable than patient’s perception when T-Scan III is used as a gold standard.

AIM: This study aimed to attempt to introduce a new extracranial horizontal plane of the head (K plane that extends from SN to SAE bilaterally) that could act as a substitute to the Frankfurt horizontal intracranial reference plane; both clinically and radiographically.MATERIAL AND METHODS: The new K plane depended on three points of the head. The first was the soft tissue nasion (NS) on the interpupillary line when the subject looked forward at a distant point at eye level. The other two points were the superior attachments of the ears (SAE).RESULTS: The student “t” test comparing mean values of K/V and FH/V was not significant; -0.21. The coefficient of correlation between different variables was highly positively significant (r = 0.98 with probability = 0.001).CONCLUSION: Within the limitations of this prospective study, the new K plane was found to be both reliable and reproducible. It can be used as a reliable reference plane instead of Frankfort horizontal plane both clinically and radiographically; as it is an accurate tool for head orientation in the natural head position.

INTRODUCTION: Intranasal corticosteroids sprays (INCS) are first line treatment for allergic rhinitis and are frequently used for chronic rhinosinusitis. Improperly aiming INCS increases the risk of epistaxis and may decrease the efficacy of the medication. The goal of this study was to determine how patients position INCS for drug delivery and if verbal or written instructions improve their positioning. METHODS: Patients in rhinology clinics were photographed while administering a generic spray bottle. The angle of the spray bot- tle relative to the patients’ head and a fixed background was determined. RESULTS: A total of 46 participants were included. The average spray angle for the right naris was 10.1o towards the septum and 67.2o below the Frankfurt Horizontal plane. The average spray angle for the left naris was 4.5o towards the septum and 62.2o below the Frankfurt horizontal plane. The angle of the spray bottle ranged from 50o toward the septum to 43o away from the sep- tum. Only 8 patients aimed away from the septum for both nares. Patients who recalled receiving verbal and written instructions aimed the INCS bottle at the lateral wall and inferior turbinate in contrast to patients who only received one form of instruction or no instructions. CONCLUSIONS: Most patients (83%) incorrectly aim INCS when compared to current guidelines. There was statistically significant improvement in the positioning of patients who reported receiving both verbal and written instruction; however, this study high- lights a greater need for patient education.

AbstractAlloplastic facial transplantation has become a new rung on the proverbial reconstructive ladder for severe facial wounds in the past couple of decades. Since the first transfer including bony components in 2006, numerous facial allotransplantations across many countries have been successfully performed, many incorporating multiple bony elements of the face. There are many unique considerations to facial transplantation of bone, however, beyond the considerations of simple soft tissue transfer. Herein, we review the current literature and considerations specific to bony facial transplantation focusing on the pertinent surgical anatomy, preoperative planning needs, intraoperative harvest and inset considerations, and postoperative protocols.

The Ideal

Abstract Esthetics has been an ever-evolving concept and has gained considerable importance in the field of orthodontics in the last few decades. The re-emergence of the soft tissue paradigm has further catapulted the interest of the orthodontist. So much so that achieving a harmonious profile and an esthetically pleasing smile has become the ideal goal of treatment and is no longer secondary to achieving a functional dental occlusion and/or a rigid adherence to skeletal and dental norms. Esthetics in the orthodontic sense can be divided into three categories: macroesthetics, miniesthetics, and microesthetics. Macroesthetics includes the evaluation of the face and involves frontal assessment and profile analysis. The frontal assessment involves assessment of facial proportions, while the profile analysis involves evaluation of anterior–posterior position of jaws, mandibular plane, and incisor prominence and lip posture. Miniesthetics involves study of the smile framework involving the vertical tooth–lip relationship, smile type, transverse dimensions of smile, smile arc, and midline. Microesthetics involves the assessment of tooth proportions, height-width relationships, connectors and embrasures, gingival contours and heights, and tooth shade and color. The harmony between these factors enables an orthodontist to achieve the idealized esthetic result and hence these parameters deserve due consideration. The importance placed on a pleasing profile cannot be undermined and the orthodontist should aim for a harmonious facial profile over rigid adherence to standard average cephalometric norms. This article aims to give an overview of the macro, mini, and microesthetic considerations in relation to orthodontic diagnosis and treatment planning.

AbstractNecrotizing fasciitis (NF) is part of the class of necrotizing soft tissue infections characterized by rapid fascial spread and necrosis of the skin, subcutaneous tissue, and superficial fascia. If left untreated, NF can rapidly deteriorate into multiorgan shock and systemic failure. NF most commonly infects the trunk and lower extremities, although it can sometimes present in the head and neck region. This review provides an overview of NF as it relates specifically to the head and neck region, including its associated clinical features and options for treatment. Noma, a related but relatively unknown disease, is then described along with its relationship with severe poverty.

Experience Pain

Osteomyelitis of the mandible is a rare condition and it could be a serious complication of untreated odontogenic infection. Classically, patient with osteomyelitis of the mandible would experience pain and swelling over the affected side of the face. CT is usually indicated when there is extension of the infection into the adjacent soft tissue and fascial spaces which could be the presenting clinical symptom. Hereby, we present a case of mandibular osteomyelitis in an 11 year old girl who presented with pain and swelling in left lower jaw followed by extraction of tooth, diagnosed on CT followed by surgical management.
