ABSTRACT
Flabby ridges are a common challenge in the prosthetic rehabilitation of edentulous patients. These mobile, hyperplastic tissues compromise denture stability and retention, leading to patient discomfort and functional limitations. This case report describes the management of an 81-year-old edentulous patient presenting with flabby maxillary tissues. The proposed treatment included a combined surgical and prosthetic approach. A specific impression technique was used to accurately record the flabby tissues with minimal displacement, employing selective pressure. Surgical intervention involved vestibuloplasty and excision of the hyperplastic mucosa, guided by a transparent duplicate of the prosthesis serving as a surgical guide. Post-surgical stabilization was achieved using a tissue conditioner applied to the final prosthesis, which was placed immediately after surgery. The healing process was monitored at regular intervals, and satisfactory outcomes were obtained with prosthesis stability, and patient satisfaction. This case illustrates the value of a multidisciplinary approach combining careful diagnosis, patient-specific impression techniques, and surgical precision to manage flabby ridges effectively and restore prosthetic function in edentulous patients.

ABSTRACT
Introduction: Lingual gingival recession is an uncommon condition that can lead to dentin hypersensitivity, impaired oral hygiene, and a risk of progression, including root surface exposure, clinical attachment loss, and reduction of keratinized mucosa width. Due to the anatomical complexity of the lingual area, its treatment poses a significant challenge. Currently, there are no standardized surgical protocols specifically designed for this condition, and the literature on the topic remains limited. Objective: To achieve root coverage of lingual gingival recessions using a minimally invasive full-thickness tunneling technique combined with a subepithelial connective tissue graft and coronal advancement of the flap. Case Report: A 35-year-old male patient, ASA I, presented with RT1-type lingual gingival recessions in teeth 33 to 43. The treatment involved a full thickness tunneling technique with a subepithelial connective tissue graft and coronal flap advancement. Complete root coverage was achieved, along with increased gingival thickness and resolution of dentin hypersensitivity. Conclusion: The full-thickness tunneling technique combined with a connective tissue graft represents a safe and effective treatment option for the management of lingual gingival recessions.

ABSTRACT
This is the case of a 60-year-old patient who required implant rehabilitation in the posterior sector of the maxilla. Given the presence of an atrophic bone ridge, a two-stage surgical approach was chosen. In the first phase, post-extraction alveolar preservation of tooth #16 was performed using the Bartee technique, placing a bone graft in the alveolus and covering it with a non-resorbable polytetrafluoroethylene (PTFE) membrane to maintain graft stability. Closure was achieved with a 5-0 nylon cross suture. Seven months following the preservation and after a computed tomographic evaluation (CBCT), a vertical deficiency of the bone crest was identified that required a maxillary sinus elevation using the lateral window technique. The lateral sinus wall was accessed with piezoelectric instruments, a bony window was created, and the sinus membrane was carefully elevated. Bone graft material covered with a resorbable membrane was placed in the resulting space to facilitate healing and stability of the graft. This case highlights the importance of sequential management of atrophic ridge bone as a key factor in optimizing bone volume and enabling predictable dental implant placement, especially in anatomically compromised posterior maxillary regions.

ABSTRACT
After tooth loss, the alveolar ridge collapses. Tooth absence often involves defects in soft tissue and hard tissue thickness. Localized defects in alveolar ridge are often found in partially edentulous patients. Soft tissue augmentation procedures have been developed. This case study presents a 50-year-old female patient who sought rehabilitation of a missing maxillary fisrt premolar (tooth 24) lost due to trauma. After diagnosing periodontal health and confirming the absence of tooth 24 through clinical and radiographic examinations, a comprehensive treatment plan was developed. The initial periodontal phase involved biofilm control and mechanical debridement, followed by a re-evaluation after two weeks, confirming periodontal health. The surgical phase included soft tissue management using the roll-flap technique after guided implant placement using a Straumann Bone Level Tapered implant (4.1mm x 10mm). A provisional restoration was placed to sculpt the emergence profile over four months. The technique resulted in excellent implant stability, that improved gingival thickness and contour.

ABSTRACT
Centric relation plays significant role in establishing dental occlusion in artificial prosthesis, while at the same time it cannot be violated by any restorative procedures. Across various times of dental prosthodontic evolution, the centric relation has been defined in different contexts with an attempt to make it more clinically understandable. In the past few decades, with the evolution of digital dentistry, there has also been significant developments in computer related graphics and simulation which has led to better understanding of difficult scientific interpretations. This article in the form of a review has been aimed to appraise the current literature related to centric relation in terms of its definitions, methods and clinical complications. The review also attempts to review most common method of recording centric relation.

ABSTRACT
A rare adenomatoid odontogenic tumor (AOT) was reported by a young 14-year-old female student that was associated with missing teeth. The patient did not have any significant medical or dental abnormalities except for a swelling in the right side of the face. Radiographic investigations showed a mixed radiolucent and radiopaque lesion associated with few missing teeth. The maxillary sinus was obliterated. The lesion was surgically excised, and a histopathological examination confirmed the diagnosis of AOT. The patient was later successfully rehabilitated with a removable partial prosthesis.

ABSTRACT
Complete removal of old filling material is essential for successful endodontic retreatment. While a variety of techniques—such as hand files, rotary NiTi instruments, ultrasonic devices, and lasers—are available, none are fully effective, particularly in anatomically complex oval-shaped canals. Supplementary instruments have been introduced to improve outcomes. This study evaluated the efficacy of the XP-Endo Finisher R (XPEF-R) in removing root canal filling material after retreatment with three different NiTi rotary systems: ProTaper Universal Retreatment (PTUR), ProTaper Next (PTN), and WaveOne Gold (WOG). A total of 36 extracted mandibular incisors with single, straight, oval-shaped canals were standardized and initially prepared using the XP Endo Shaper system. The canals were obturated with gutta-percha and AH Plus sealer using warm vertical compaction. Specimens were divided into three groups (n=12) and retreated with PTUR, PTN, or WOG. Micro-CT scans were used to measure the volume of residual filling material. Following this, all samples underwent supplementary instrumentation with XPEF-R. Statistical analysis was conducted using the Kruskal-Wallis nonparametric test. The greatest volume of material was removed from the full canal length, though differences among canal sections were not statistically significant. PTUR showed the most effective performance across all levels. While XPEF-R further reduced residual material, the reduction was not statistically significant (p > 0.05). The PTUR and XPEF-R combination yielded the best results, but not significantly better than the other groups. In conclusion, the combination of the XP-Endo Finisher R with other rotary Ni-Ti systems is effective for the retreatment of oval-shaped canals, with the ProTaper Universal Retreatment system being superior.
