Amelioration of Pathological Tooth Migration by Surgical Periodontal Therapy Alone: A Stupendous Clinical Case Report with Two Year Follow up

Moderate-to-severe form of periodontitis is often accompanied by pathological tooth migration. This is characterized by spacing and proclination of teeth. Patients often feel awkward regarding their facial esthetics and seek treatment for the same. Pathological tooth migration is a complex puzzle with various etiological factors to its credit. Treatment often involves time-consuming interdisciplinary approach. Very few case reports have achieved complete resolution of pathological tooth migration by periodontal therapy alone. In this unique case report, periodontal therapy alone could ameliorate pathological tooth migration. Further to it, results are stable for 2 years and continue to be so. Hence, meticulous periodontal therapy is effective in the management of pathologic tooth migration.

CORRELATION BETWEEN UPPER LIP MORPHOLOGY AND PROCLINATION OF ANTERIOR TEETH IN PATIENTS REPORTING FOR ORTHODONTIC TREATMENT

Introduction: Orthodontic treatment is performed to enhance one's aesthetics and morphological harmony and also to improve the function of the oral and maxillofacial region. Soft tissue analysis has always been an integral important part of diagnosis and treatment planning. Lip position has become one among the foremost important soft tissue analysis because it influences the occlusion, tooth stability and facial aesthetics. The aim of this study is to find out the relationship between upper lip morphology and proclination of anterior teethMaterials and methods: It is a single centered retrospective study conducted in a private dental institution in Chennai. The samples were taken from the patients who reported to the dental outpatient department from June 2019 to February 2021. The patient records were reviewed and analyzed. Inclusion criteria included age, gender, lip competency and lip length and proclination of anterior teeth. Proclination of teeth and lip competency were all done through photographic evaluation. Patients in the age group of 18-25 years, with proclination of teeth in the upper arch and class I malocclusion were selected. A total of 513 patients were included in the study.Results and discussion: A total of 513 patients' data were collected according to the criteria. Out of 513 patients 45%(238) were males and (54.2%) 278 were females. Patients in the age group of 18-25 years were selected. However, most of the patients concentrated within a small range with the highest percentage being 24 years(15.6%) and 22 years(15.6%) followed by 23 years(14.8%). 57.7% patients had competent lips, 30.8% had incompetent lips and 11.5% had potentially competent lips. 64.3% of patients had short lip and 35.7% had normal lip length. Class I malocclusion and proclination in the maxilla were seen in all 513 patients. Chi square test was done to assess the relationship between lip competency and Lip length (p<0.05 was considered statistically significant).Conclusion: According to our study it was suggestive that there is a relationship between the upper lip morphology and proclination of anterior teeth.

Molar distalization classification – A review

Esthetics plays a major role from orthodontic treatment to results. Gaining space in dental arch is the most important step in the treatment planning which can be achieved by different methods one of which is molar distalisation. There are a number of methods (Arch expansion, interproximal reduction, proclination of teeth, molar derotation, use of functional appliances) to gain space. Each method has its own advantages and disadvantages and specific indications. A child with class I bases and acceptable profile, with minimal space requirements for relief of crowding or mild protrusion can possibly be best treated without sacrifice of tooth material. Various intaoral and extraoral appliances have been invented using non-extraction treatment to distalise molars. Aim of distalization is to move molars distally so as to gain space. This article provides a comprehensive review of the various methods (intraoral & extraoral) used for molar distalization.

Evaluation of displacements and stress changes in the maxillo-mandibular complex with fixed functional appliance skeletally anchored on mandible using miniplates: A finite element study.

OBJECTIVES:Fixed functional appliances (FFA) have been used for correction class II malocclusion but cause proclination of teeth. Recently, few studies have advocated the use of skeletal anchorage along with FFAs to prevent this side effect. The purpose of the study was to evaluate the stress distribution and displacements produced by miniplate anchored Forsus-fatigue resistant device on the maxilla, mandible, and the dentition in a Class II malocclusion patient by finite element analysis.MATERIALS AND METHODS:Cone beam computed tomography of a class II division 1 patient indicated for FFA was used to construct a 3D finite element model using MIMICS 8.11 and Hypermesh 13.0 software. Various material properties, boundary, and loading conditions were then applied. The model was analyzed for principal stress and von Mises stress in maxilla, mandible, and their dentition using ANSYS 12.1 software.RESULTS:In the mandible, maximum principal and von Mises stresses were seen in the cortical bone area in the symphyseal region, whereas mandibular teeth showed comparatively lesser stresses. In the maxilla, higher principal and von Mises stresses were seen in the maxillary molar region compared to the maxillary cortical bone. The entire mandible was displaced antero-inferiorly, whereas the maxilla showed a postero-superior displacement.CONCLUSION:Using skeletally anchored FFA results in more stresses and displacements in the skeletal structures compared to the dentition.

Pre-prosthetic Orthodontic Implant for an Aesthetic Rehabilitation : A Case Report

A combination of dental problems such as missing teeth, proclination of teeth and occlusal problems cannot be satisfactorily treated by prosthodontic approach alone. The rehabilitation of patients requiring an esthetic smile demands the collaboration of multiple dental specialists. the need for orthodontic tooth movement prior to restorative treatment is necessary for some patients, in order to optimize both esthetic and functional aspects of dental treatment.The present case report achieved successful implant based oral rehabilitation in a patient with absence of the right maxillary central incisor utilizing a preprosthetic orthodontic implant site preparation for the purpose of space gain.

Patient reporting for anterior tooth alignment during ugly Duckling stage - A mishap

Ugly duckling stage is a self-correcting anomaly seen during the mixed dentition period. It is characterised by the spacing between the upper incisors and proclination of teeth. It is seen that during this stage, parents take their child to the dentist to correct the malaligned teeth due to unawareness. The aim of this study is to assess the prevalence of pediatric dental patients reporting for tooth alignment during the ugly duckling stage. This retrospective cross-sectional study included patients who reported to saveetha dental college during June 2019- March 2020. Case records of about 10,000 patients were reviewed and 3363 patients were recruited under 8 to 13 years of age. Statistical analysis was done using SPSS software version 20.0. About 50.8% of patients who belonged to the age of 10 years reported for tooth alignment during an ugly duckling stage. Results were statistically significant for the association between age and chief complaint of anterior tooth alignment (p<0.05). Thus, the role of the dentists lies in making the parents aware that the ugly duckling stage is a self-correcting phenomenon and no orthodontic correction is required during this stage.

Diastema closure and aesthetic rehabilitation; An interdisciplinary approach

Midline diastema is a common problem amongst the adults which has a great impact on the aesthetics. Common causes for the development of such a condition include high frenum attachment, proclination of teeth, dentoalveolar disproportion etc. The treatment of such condition requires accurate diagnosis of aetiology and its elimination followed by space closure using orthodontic modalities. This case report presents a case of 20 year old female patient with the chief complaint of space between the upper front teeth. High frenum attachment was diagnosed as primary aetiology and was eliminated by laser assisted frenectomy. The space closure was accomplished using orthodontic treatment. One year follow up showed a satisfactory outcome with complete closure of midline diastema and rehabilitation of aesthetics.

A New Index Proposed for Determination of Outcome of Recession Coverage Procedures

Focused Clinical Question: How can the clinical outcome of recession coverage procedures be determined in cases of malaligned and rotated teeth?Summary: The primary impetus that led to the development of the various indices of gingival recession coverage procedures was to correlate the prognosis to the anatomic features. Two important anatomic features, i.e. rotation and proclination of teeth, affect the topography of the labial bony plate as well as the biotype of the soft tissue overlying the root surface and consequently the treatment outcome. The purpose of this article is to propose an index for predetermination of the outcome of gingival recession coverage procedures, depending on the extent of rotation or proclination of the teeth to be treated. The study population consisted of 12 patients (22 sites) with Miller Class I and Class II recession of mandibular/maxillary teeth. These recession defects were treated with subepithelial connective tissue graft procedures. Clinical parameters assessed were percentage of recession coverage achieved at 6 months post‐surgically. A malalignment index (MI) was devised and interpreted for its prognostic value with respect to the treatment executed for the recession coverage procedure. The Pearson correlation between percentages of recession coverage achieved and the MI scores assessed was 0.015, which is statistically significant.Conclusion: This clinical study concludes that the proposed MI will be of high prognostic value, in predetermination of the success of the root recession coverage procedures in proclined and rotated teeth.

Evaluation of Orofacial Manifestations in 50 Thalassemic Patients: A Clinical Study

Background and Objectives: Thalassemia has been reported as a high prevalence genetic disorder with some oromaxillofacial complications. The aim of this study was to evaluate the prevalence of oromaxillofacial disorders in thalassemia patients and to detect the presence of any correlation between the orofacial manifestations and the hematological picture/systemic findings.Materials and Methods: A total of 50 thalassemic, 36 with thalassemia major and 14 with thalassemia minor were selected from the hematology Department of Lokmanya Tilak Medical College and Government (LTMG) Hospital, Sion, Mumbai.Results: The most prominent features included, skull bossing seen in 74% of the patients, hypertelorism, depressed bridge of the nose, prominent malar bones, pallor of oral mucosa, gingival pigmentation and proclination of teeth. Splenomegaly, hepatomegaly and cardiovascular changes were also commonly seen. The blood picture showed for a low mean Hb value of 6.63 gm/dl. Microcytosis, anisocytosis, hypochromasia and poikilocytosis was seen in the blood smear. Hemoglobin electrophoresis patterns revealed raise HbF and HbA2 levels.Conclusions: This study showed that about 84% (42 cases) of all patients under consideration showed changes in oral and maxillofacial complications including upper and lower jaw protrusion, saddle nose, space between anterior teeth, anterior teeth protrusion, and frontal bossing. It was noted that the severity of orofacial manifestations increased with a decline in the systemic health and a deterioration in the blood picture. Also, it was revealed that the rate of prevalence for oral and maxillofacial complications decreases when patients receive blood at younger ages.

Mandibular incisor position changes in relation to amount of bite jumping during Herbst/multibracket appliance treatment: A radiographic-cephalometric study

The aim of this study was to analyze the effect of the cast Herbst/multibracket (MB) appliance on the position of the mandibular incisors in relation to the amount of mandibular advancement at the beginning of treatment. We screened 133 patients with Class II Division 1 malocclusions. The subjects were divided into 3 bite-jumping groups: I, 49 subjects with bite jumping of <7 mm; II, 44 subjects with bite jumping of 7.5 to 9.5 mm; and III, 40 subjects with bite jumping of >9.5 mm. Only group I with small (S) and group III with large (L) bite jumping were considered. The average ages of the subjects in the 2 bite-jumping groups were 13.6 +/- 2.4 years in the S group and 14.7 +/- 4.7 years in the L group. The average treatment time with the Herbst/MB appliance was 19 months. Lateral headfilms were evaluated at 3 times: before Herbst treatment, after Herbst treatment, and after MB treatment. During the Herbst phase, the mandibular incisors were significantly intruded, protruded, and proclined in both bite-jumping groups. Larger tooth movements occurred in group L than in group S. During the MB phase, comparable relapsing incisor tooth movements were seen in the 2 bite-jumping groups. There was moderate correlation between bite-jumping and incisor position changes during the Herbst and the Herbst/MB treatment periods. No associations were found between the amount of bite jumping and the changes of sagittal and vertical jaw relationships, age, and treatment growth period. During the Herbst treatment period, there was an association between bite jumping and movement of the mandibular incisors: the greater the bite jumping, the larger the intrusion, protrusion, and proclination of teeth. During the MB treatment period, relapsing incisor tooth movements occurred that were independent of the original amount of bite jumping.
