ABSTRACT
Background: The restoration of the anterior maxilla with implants requires precise techniques to ensure aesthetic outcomes. Immediate implant placement with provisional restoration is a commonly used method to preserve soft tissue and maintain esthetics. Observation: A 40-year-old male patient with a severely decayed maxillary lateral incisor (tooth 22) underwent immediate implant placement following extraction. A resin-based indexing key was fabricated pre-surgery to guide implant positioning. A provisional restoration was placed, and a corrected model was created for final restoration. Radiographic control confirmed the proper positioning. Conclusion: This case illustrates the effectiveness of the corrected model technique combined with digital workflows (CAD/CAM and intraoral scanning) for immediate implant placement and provisional restoration, achieving both aesthetic and functional success.

ABSTRACT
Upper airway obstruction refers to difficulty breathing through the upper respiratory tract, including the nostrils, mouth, pharynx, and larynx. This condition can be caused by factors like nasal congestion, allergies, septal deviation, and the presence of polyps in the paranasal sinuses. Nasal polyps can lead to symptoms such as persistent nasal congestion, difficulty breathing through the nose, and loss of smell. As a result, individuals may breathe through their mouths, which can lead to a low tongue position and an "adenoidal facies," characterized by an elongated face. Additionally, changes in the stomatognathic system, such as a reduced upper dental arch, malocclusions, and clockwise mandibular growth, may be observed. This study aims to explore the correlation between nasal polyps and skeletal patterns. Clinical records from 147 orthodontic patients at the Faculty of Dentistry, Mexicali, were analyzed. Information gathered included gender, skeletal class (I, II, or III), and facial biotype (dolichofacial, mesofacial, or brachyfacial). CBCT images were obtained, and various parameters, including the Jarabak index and nasal polyp presence, were analyzed. The results revealed that mesofacial biotype was the most common (40%), and skeletal Class II predominated (48%). A counterclockwise growth pattern was observed in 50% of patients, while 79% had no nasal polyps. The study concluded that no significant correlation was found between nasal polyps, skeletal class, and facial pattern. However, the absence of polyps was more common in mesofacial patients and those with skeletal Class II. The study recommends further research with larger sample sizes and standardized data collection methods to confirm these findings.

ABSTRACT
Gingival health is crucial to the longevity of natural teeth and the surrounding periodontium, especially when the teeth are restored. Fixed partial dentures that replace missing tooth/teeth utilise natural abutment teeth to retain the prosthesis. During impression procedures, it's crucial to replicate the margin of the restoration, an important landmark. Over the last decade, digital dentistry has introduced a vast range of new materials to the field of dentistry. Many new materials for gingival retraction procedures have also been introduced that work on different principles than conventional retraction cords. This review was aimed at appraising the recent evidence for which the literature search between the years 2010 and present was performed. Many new materials and refinements of chemicals used along with retraction cords have been investigated, which have been more advantageous clinically while causing less harm to the gingiva.

ABSTRACT
: Introduction: Cantilevered anterior fixed partial dentures (FPDs) are a viable treatment option for patients with esthetic concerns, particularly when implants are not suitable due to medical conditions or financial constraints. These prostheses provide a conservative, minimally invasive solution to restore both function and appearance. Objective: This case report aims to demonstrate the use of a cantilevered anterior FPD for esthetic rehabilitation in a medically compromised patient undergoing radiotherapy for breast cancer, with a focus on achieving an optimal esthetic result while considering the patient's medical and financial limitations. Patient and Methods: A 42-year-old female patient presented with severe mobility of tooth 12 and a 1mm midline diastema. After initial periodontal therapy (scaling and root planing), the treatment plan was established. The adjacent teeth (11 and 21) were prepared for full coverage crowns, and tooth 12 was extracted atraumatically. An immediate provisional cantilever bridge was placed, followed by final impressions for the fabrication of a ceramo-ceramic cantilever bridge with tooth 22 in extension. Results: The final prosthesis successfully restored the patient's smile, providing immediate esthetic improvement and functional stability. The cantilevered bridge with tooth 22 in extension closed the midline diastema, with no complications observed during the healing phase. The patient expressed high satisfaction with the esthetic outcomes and functional restoration. Conclusion: This case highlights the effectiveness of cantilevered anterior FPDs as an esthetic and functional solution for patients with medical conditions that preclude implant therapy. The treatment was minimally invasive, cost-effective, and met the patient’s needs for a rapid, non-surgical approach. Cantilevered bridges offer a viable alternative for esthetic rehabilitation in medically compromised patients, though further research is needed to assess ...

ABSTRACT
Introduction: Achieving optimal esthetic integration of fixed prostheses in the anterior region requires effective periodontal management. This case report demonstrates the use of surgery-guided techniques to enhance esthetic outcomes in a prosthetic rehabilitation. Observation: A patient with insufficient clinical crown height underwent crown lengthening and subepithelial connective tissue grafting for soft tissue optimization. CAD/CAM technology was used to fabricate a provisional prosthesis, ensuring precise fit and esthetic integration. Discussion: Surgery-guided periodontal techniques, including crown lengthening and soft tissue grafting, improve esthetic outcomes by optimizing gingival contours. The use of digital workflows enhances precision, but challenges remain in managing gingival healing and achieving ideal esthetics. Further research into advanced materials and technologies could further refine this approach.

ABSTRACT
Aim & Objective: Nanotechnology is a field growing as a major influencer in the health community in recent times. In dentistry, particularly Periodontics, nanotechnology promises great strides in diagnostics, therapeutic strategies and treatment efficacy. Using the specific features of nanomaterials, which involve, their small size, ability to cover large areas while occupying very little space and the chemical attributes that can be changed very easily by the scientists, are some of the innovative approaches towards nanomaterials being used to handle the multifaceted nature of periodontal diseases. This essay examines how nanotechnology is used in periodontology at the cutting edge level with emphasis on how it could redefine preventive practices, diagnostic procedures and curative interventions resulting in positive oral health outcomes. Material & Method: The review adopts a systematic approach to scrutinize the current literature on the employment of nanotechnology in periodontics. A rigorous search through reputable databases identified peer-reviewed articles that met established inclusion criteria. The use of terms such as nanomaterials in periodontal diagnostics, treatments and therapeutics was targeted for data extraction. The study reviews the incorporation of nanotechnology into periodontology with the aim of giving useful information on this new technology. Result: Nanotechnology is widely applied in periodontics and this can be seen from all the literatures. Nanomaterials help in diagnosis, deliver drugs to target cells, and improve tissue repair. Such a discovery points towards the probability of nanotechnology revolutionizing the dental care.

ABSTRACT
Temporomandibular joint (TMJ) ankylosis is a condition where the mandible is fused to the fossa, causing discomfort and potentially life-threatening issues. Factors include trauma, odontogenic and non odontogenic infections, prior surgical interventions, congenital defects, iatrogenic/idiopathic causes, with trauma being the most common cause. Treatment is mainly surgical, followed by long-term physiotherapy, preferably through a trismus opening appliance. We present a case of a young female patient who was surgically treated for right-side TMJ ankylosis. The patient had a limited mouth opening, which made impression making difficult. A double-sided, spring-loaded expansion appliance was fabricated that was customised to the patient's occlusal surfaces of maxillary and mandibular arches. The appliance was difficult to wear initially, but after continuous expansion over a time period, the trismus was relieved and normal mandibular movements were restored. Patient was thoroughly satisfied with the outcome of the treatment.
