From Function to Aesthetics: The Dual Impact of Orthognathic Surgery
Orthognathic surgery is a treatment approach that provides not only functional improvements but also significant enhancements in facial aesthetics by correcting skeletal discrepancies of the jaws. This presentation will focus on the dual interaction between the functional and aesthetic aspects of orthognathic surgery, discussing current literature and up-to-date data.
Orthognathic surgery considers function and aesthetics not as separate entities, but as two complementary components. While the procedure has functional effects on mastication, respiration, speech, and overall quality of life, its aesthetic contributions to facial proportions and profile balance should also be emphasized. Therefore, these proportions and balances must be carefully evaluated during preoperative planning. Today, with the support of digital surgical planning techniques, when combined with appropriate surgical methods, this approach provides the most ideal and long-lasting postoperative outcomes.

Education
Accuracy of Surgical Guides in the Digital Planning Era
Computer-assisted implantology represents one of the most significant advancements in the digital transformation of dentistry, enabling surgical planning to become more predictable and precise. Through the integration of cone beam computed tomography (CBCT), digital scanning systems, and specialized planning software, this approach allows for highly accurate implant placement. The guiding systems used in digital implantology are generally categorized as dynamic and static. Dynamic systems support implant positioning through real-time navigation, whereas static systems transfer the digitally planned implant position to the oral cavity via custom-fabricated surgical guides. Static guided surgery has become widely preferred in clinical practice due to its advantages, such as improved planning precision, reduced operation time, and minimized surgical trauma. However, factors such as the algorithmic structure of the software, the method of guide fabrication, and the precision of data processing can directly influence the accuracy of implant placement.
Keywords: digital implantology, dental implant, guided surgery.

Vestibuloplasty and Repositional Flap: A New Technique
Severe alveolar ridge resorption leads to a reduction in vestibular depth and loss of keratinized mucosa, adversely affecting prosthesis stability and soft tissue health. In such cases, vestibuloplasty combined with excision of the hypermobile mucosa is often preferred; however, this approach may result in the complete loss of existing keratinized tissue.
This presentation introduces the Pedicled Repositional Split-Flap Technique, which eliminates the need for a donor site and enables the repositioning of keratinized, hypermobile mucosa onto the alveolar ridge. The technique is combined with Clark’s vestibuloplasty, allowing simultaneous deepening of the vestibule and increasing the amount of keratinized mucosa while achieving tissue gain without the need for a second surgical site.
In the treated cases, an average gain of 7 mm of immobile keratinized mucosa was achieved. The repositioned tissue maintained its keratinized character and stability throughout the follow-up period.
This method provides an effective, safe, and low-morbidity alternative for creating a stable soft tissue surface in severely resorbed mandibles, either before prosthetic rehabilitation or to increase the amount of keratinized mucosa in implant-planned regions.

Vertical Alveolar Ridge Augmentation Using the Shell Technique: Surgical Technique and Clinical Pearls
Vertical alveolar ridge deficiencies can compromise implant placement, often necessitating additional surgical interventions such as nerve lateralization or vertical bone augmentation. Among various bone augmentation techniques, vertical ridge augmentation is one of the challenging procedures in implant dentistry because it requires high surgical precision and is performed outside the natural bone envelope, in an area with poor vascularity. Careful surgical planning and effective soft tissue management are essential to achieve successful outcomes.
In the shell technique, thin cortical bone plates are placed vertically to the residual alveolar ridge and stabilized at the level of the crest. The space created between the lamellae is filled with particulate bone graft material.
Several clinical principles are essential for the success of this technique. Proper case selection and thorough evaluation of the donor site are the primary considerations for a successful outcome. In addition, adequate flap design, precise splitting and shaping of the harvested bone, correct positioning and rigid fixation of the cortical lamellae at the desired height and contour, appropriate choice of graft material, and tension-free flap closure are all critical factors influencing the success of the procedure.
The main disadvantages of vertical bone augmentation using the shell technique are intraoral donor site morbidity and the prolonged edentulous period. However, despite these drawbacks, the technique offers numerous advantages. When performed carefully, it enables predictable vertical bone reconstruction and regeneration of the alveolar ridge, thereby creating ideal conditions for implant placement and prosthetic rehabilitation. In this presentation, the fundamental principles of vertical alveolar ridge augmentation using the shell technique, the surgical workflow, and key clinical tips that enhance treatment success will be presented, and the advantages and disadvantages of this technique will be discussed in comparison with other vertical augmentation methods.

Clinical Tips in Temporomandibular Joint Lavage
Temporomandibular joint (TMJ) disorders are common clinical conditions with a multifactorial etiology that affect the functional integrity of the masticatory system. In cases where conservative treatment fails to achieve satisfactory improvement, TMJ lavage (arthrocentesis) emerges as an effective and minimally invasive treatment option. Arthrocentesis is based on the principle of irrigating the superior joint space with physiological saline or lactated Ringer’s solution. The procedure aims to remove inflammatory mediators, reduce intra-articular pressure, and mechanically release adhesions within the joint. Clinical success is closely associated with appropriate case selection, a thorough understanding of TMJ anatomy, correct needle insertion angles, and adequate lavage volume. Clinical observations and data from the literature indicate that TMJ lavage provides high success rates in reducing pain and improving mouth opening, particularly in early-stage internal derangements. Furthermore, combining lavage with intra-articular injections (such as hyaluronic acid or corticosteroids) may enhance long-term symptom control. The purpose of this presentation is to share clinical tips for improving the success of TMJ lavage procedures and to present practical recommendations based on current evidence in the literature.

The Surgical Spectrum of Ameloblastoma: A Patient-Specific Strategic Approach
Ameloblastoma is a locally aggressive benign tumor of epithelial origin, representing a considerable proportion of odontogenic lesions in the maxillofacial region. Clinically, ameloblastoma typically presents as a slow-growing, painless swelling that causes cortical bone expansion. Over time, this may lead to functional impairment and aesthetic deformity. Diagnosis is often delayed, likely due to its indolent growth pattern.
Despite its benign nature, ameloblastoma exhibits aggressive behavior and is associated with a high risk of recurrence. Management strategies range from conservative procedures, such as enucleation, curettage, and marsupialization, to radical approaches including marginal or segmental resection. In some cases, Carnoy’s solution is applied as an adjunct to conservative surgery to reduce the risk of recurrence. The choice of surgical technique depends on multiple factors, including tumor type, size, location, clinical behavior, and patient-related considerations such as age and socioeconomic status.
Conservative techniques may be appropriate for less aggressive lesions and offer advantages such as shorter operative time, faster recovery, and simpler reconstruction, although they have been associated with higher recurrence rates. Radical surgery is generally preferred for aggressive lesions, achieving lower recurrence but often resulting in significant hard and soft tissue defects. These consequences may complicate subsequent reconstruction aimed at restoring both function and appearance. Reconstruction techniques include autologous bone grafts, free vascularized flaps, and alloplastic materials. In resections involving the condylar region, temporomandibular joint prostheses provide functional stability and anatomical compatibility.
This presentation reviews various surgical approaches applied to ameloblastoma cases treated in our clinic and highlights the potential role of tailoring the surgical strategy to patient and lesion-specific characteristics in reducing recurrence risk, preserving functional structures, and improving aesthetic outcomes.
