Strategic Intervention: Ectopic Premolar Management for Preventing Molar-Premolar Transposition in Class III Malocclusion.

Class III malocclusion often leads to the ectopic eruption of premolars in the upper arch, posing unique challenges for orthodontic practitioners. This case report explores the clinical implications of ectopic maxillary premolars in a Class III malocclusion patient, emphasizing the importance of early intervention and comprehensive treatment strategies. Factors contributing to ectopic eruption, including genetic predisposition and anatomical variations, are discussed, guiding orthodontists in effective diagnosis and management. A 14-year-old patient with Class III malocclusion, anterior crossbite, and ectopic maxillary premolars sought orthodontic consultation. The treatment plan involved extracting the deciduous second molar, realigning the ectopic premolar, and addressing arch length discrepancies. Utilizing fixed orthodontic appliances and strategic force application, the patient achieved Class I molar and canine relationships, resolving the ectopic premolar alignment within 10 months. Ectopic eruption of maxillary premolars, especially in Class III malocclusion, is a critical concern for oral health. Genetic predisposition, arch crowding, and developmental disturbances contribute to this condition. Early intervention, as demonstrated in this case, plays a pivotal role in restoring dentoskeletal harmony. The study underscores the need for a multidisciplinary approach, combining orthodontic, surgical, and restorative interventions for optimal outcomes. Thus, this case report highlights the successful management of ectopic maxillary premolars in a Class III malocclusion patient through strategic orthodontic intervention. Understanding the etiological factors and employing a comprehensive treatment approach facilitate timely diagnosis and prevent complications. Orthodontists must navigate the complexities of ectopic eruption, considering occlusal effects and collaborating with other specialists for holistic patient care.

Mini-Screw-Assisted Orthodontic Retraction of Class I Malocclusion in a Bimaxillary Protrusion Patient Using Sliding Mechanics: A Case Report.

A condition known as bimaxillary protrusion occurs when the front teeth protrude due to the forward positioning of the lower and upper jaws. Temporary anchorage devices (TADs) are utilized to provide anchorage and facilitate the controlled retraction of maxillary and mandibular protruding teeth, helping to correct the patient's bite and facial aesthetics. A 27-year-old female with bimaxillary protrusion reported to the Department of Orthodontics. On examination, the facial profile of the patient was convex. The clinical FMA was high. With a deep mentolabial sulcus and an acute nasolabial angle, lips were potentially competent. An intraoral examination revealed proclined incisors with spacing in the maxillary arch and proclined anterior teeth in the mandibular arch. Space closure was done using sliding mechanics with direct anchorage from a mini-screw after the extraction of all four first premolars. There was a significant improvement in the patient's profile posttreatment.

Simultaneous Intrusion and Retraction of Maxillary Anterior Teeth in Class II Malocclusion Using the Kalra Simultaneous Intrusion and Retraction (K-SIR) Loop: A Case Report.

The straight-wire device offers the best finishing potential and control. This case study focuses on the treatment of severe deep bite and Class II malocclusion involving first premolar extraction of the upper arch using a Kalra Simultaneous Intrusion and Retraction loop. Using minimal force and creating enough space for anterior teeth to retract while maintaining the Class II molar relationship was the aim of the therapy. Due to the unsightly excessive maxillary incisor showing at rest, the decision was made to intrude anterior teeth to treat a deep overbite. Good and consistent changes occurred post-treatment.

Unveiling the Journey: A Case Report of Managing an Impacted Central Incisor.

Although impaction of the maxillary permanent central incisor is uncommon in dentistry due to its significance to facial aesthetics which are challenging to treat. To abstain from the consequences related to aesthetic and functional occlusion, early detection of an impacted central incisor is imperative. This case report describes a male patient, aged 22 years, who had an impacted central incisor tooth in the maxillary anterior region. A surgery was performed to remove the impacted supernumerary tooth that was preventing the eruption of the central incisor. Using a combination of surgical exposure and orthodontic force, the impacted right maxillary central incisor was relocated to its proper occlusion in the dental arch.

Mean Bone Density in Interadicular Areas of Maxilla among Patients Visiting Dental Unit of a Tertiary Care Centre: A Descriptive Cross-sectional Study.

Introduction: A close relationship occurs between the type of bone density and the success of orthodontic mini-implant. The aim of this study was to find out the mean bone density in interradicular areas of the maxilla among patients visiting dental unit of a tertiary care centre. Methods: A descriptive cross-sectional study was performed at the Department of Orthodontics and Dentofacial Orthopedics at a tertiary care centre from 15 January 2022 to 28 June 2022 after taking ethical approval from the Institutional Review Committee (Reference number: UCMS/IRC/175/21). Data was collected from scan reports obtained with a computed tomography scanner. Bone density was measured at 6 mm height from the alveolar crest. Convenience sampling was done. Point estimate and 95% Confidence Interval were calculated. Results: Out of 70 patients, mean bone density at interradicular areas of maxilla was 992.31±204.20 HU (944.46-1040.13, 95% Confidence Interval). Between central and lateral incisor 50 (71.44%) had D2 type of bone density. Conclusions: The mean bone density in inter radicular areas of the maxilla among patients visiting the dental outpatient department was similar to other studies done in similar settings. Keywords: bone density; prevalence; prostheses and implants.

New design titanium miniplate versus conventional miniplate in treatment of mandibular angle fractures: A comparative study.

Introduction: Mandibular angle fracture (MAF) is the second most common site of all fractures of the mandible with the highest complication rate. Management of MAF has evolved in the past four decades. The purpose of the prospective study was to compare the efficacy of new design titanium miniplate (NDM) with conventional titanium miniplate (CTM) in the treatment of MAF. Objectives: Mouth opening, occlusion, bite force measurement, and radiographs compared preoperatively and first week, first month and third month postoperatively. Materials and Method: Fourteen patients diagnosed with MAF were randomly divided into two groups: Group A (seven patients) was treated with NDM and Group B (seven patients) with CTM. Patients were assessed preoperatively and postoperatively at an interval of one week, one month and three months. Results: Repeated measures ANOVA and Post hoc Tukey test showed a significant increase in bite force and mouth opening for both groups in first and third postoperative months. Unpaired t-test showed slightly better mouth opening in Group B and slightly higher bite force in Group A. Discussion: Both miniplates fulfilled all the study objectives and equally satisfactory healing was seen at the end of third month. NDM offers better stability, rigidity, and anatomic reduction of the fracture with a drawback of difficulty in adaptation and increased operative timing compared to CTM. Hence, we would like to conclude that both miniplates are equally efficient in the treatment of non-comminuted angle fractures with the NDM having upper hand in stability.

Analysis of Nasal Morphology in Skeletal Class I and Skeletal Class II Malocclusion: An Observational Study.

Background and objectives The nose is one of the major focuses of face attractiveness. Through careful evaluation of the soft tissue drape, a treatment plan can be designed to enhance a patient's facial attractiveness. The aim of this study was to evaluate and assess the variations in nasal morphology among class I malocclusion and class II horizontal and class II vertical malocclusion. Material and method Lateral cephalograms of 27 patients were taken and consisted of three groups: skeletal class I malocclusion, class II horizontal malocclusion, and class II vertical malocclusion. The various linear and angular measurements specific to nose were assessed. Results and conclusion In class II and class I malocclusion, the nose is observed to be straight and convex, respectively. Additionally, compared to class II horizontal malocclusion, it is more convex in class II vertical malocclusion. Vertical growers or high-angle cases are more likely to have a nose with an increased inclination toward nasal dorsum convexity than horizontal growers or low-angle instances.

Temporomandibular Joint Disorder and Airway in Class II Malocclusion: A Review.

In class II malocclusion, there is an anteroposterior disparity between the upper dentition and the lower dentition, which may or may not be accompanied by a skeletal discrepancy. For orthodontists, this is one of the common malocclusions encountered during clinical practice. This might be due to excess maxillary growth or retarded growth of the mandible or a combination of both. In such types of malocclusion, both the upper and lower airways are affected, the lower one most commonly. Characteristic features seen are a narrow maxillary arch, a proclined upper anterior, and mouth breathing as a developing habit. Also, the position of the condyle in the skeletal type of class II malocclusion plays a vital role in the development of temporomandibular joint disorders. Treating such disparity in a growing individual leads to better results in the long term as well as prevention of malocclusion taking a severe form. Myofunctional appliances are useful for repositioning the mandible as well as the condyle. In adults, extraction of the upper premolars is most commonly done for the correction of class II malocclusion. This provides the patient with a better esthetic appearance. In addition to this, various treatment modalities, such as splint therapy, exercise, and prolotherapy, are beneficial for pain relief and temporomandibular disorder (TMD) correction. This article deals with the characteristics, development, etiology, and comprehensive treatment options of class II malocclusion and its co-relation with the upper and lower airway along with the severity of temporomandibular joint disorders. Repositioning of the condyle in the glenoid fossae is the key to the correction of this disorder.

A Multidisciplinary Aesthetic Treatment Approach for Peg Lateral of the Maxillary Incisors.

Developmental anomaly of the maxillary lateral incisors most commonly leads to the occurrence of peg lateral. It is a variant of microdontia where the lateral incisors are smaller than the normal size. This appears as unilaterally or bilaterally. This condition is characterised by the converging of the mesial and distal surfaces forming a cone shape. A variety of treatment options exist for this anomaly including orthodontic treatment, restorative technique and veneer. This case report deals with an individual presenting with peg lateral of the maxillary arch along with midline diastema. The multidisciplinary treatment protocol of orthodontic treatment involving minor tooth movement and space closure in conjunction with a restorative technique for correction was preferred.
