REVIEW
R John Tannyhill, Maria J Troulis
Dental implant therapy in the non-cleft patient is familiar to most oral and maxillofacial surgeons. Understanding the differences in surgical treatment planning in the cleft patient versus the non-cleft patient is the key to highly functional and esthetic long-term outcomes. CBCT and computer-assisted planning, as well as improved technology in grafting and implant materials, result in excellent outcomes. Communication with the restorative team remains of paramount importance in planning treatment.

Bone deficiency is the major obstacle in implant dentistry. Guided bone regeneration (GBR) with particulate bone and barrier membranes has been the primary surgical technique used to regenerate alveolar bone for dental implant therapy. This procedure has been used in implant dentistry for more than 30 years and continues to be developed and refined for more predictable surgical outcomes. This article reviews GBR and alternative ride expansion procedures and reviews the use of various particulate graft materials...

Len Tolstunov
Replacement of failing and ailing natural teeth with dental implants has become a mainstream treatment option since the discovery of osseointegration by P.-I. Brånemark in the 1960s. The techniques and the variety of methods for alveolar bone reconstruction have evolved to address a restoratively driven approach in implant dentistry. Modern 3D cone-bean computed tomography has helped with the diagnosis and treatment of bone deficiencies to idealize implant positioning. This article focuses on bone augmentation techniques, classified into horizontal and vertical ridge augmentation, and discusses block grafting, guided bone regeneration particulate grafting, distraction osteogenesis, and ridge-split expansion procedures...

Three edentulous maxillary patients were treated with 9- to 15-mm advances of the maxilla by Le Fort I distraction osteogenesis combined with simultaneous sinus floor autograft placement. The patients were subsequently treated with 8 implants placed in the molar, bicuspid, and canine regions for complete arch ceramo-metal fixed restorations. Anterior emergence profile esthetics was obtained in 2 patients who had high smile lines. Following final restoration, no maxillary relapse was evident, and no implants were lost...

Bone grafting has become an integral part of implant dentistry. To achieve a predictable long-term outcome for osseointegrated implants, a sufficient volume and quality of alveolar bone must be present at implant recipient sites. Resorption of the alveolar ridge and postsurgical or post-traumatic defects of the residual alveolar bone can prevent ideal placement of a dental implant. Thus, in many cases, alveolar bone grafting is the real challenge in implant reconstruction. This article will discuss the various techniques and graft materials for alveolar ridge reconstruction of the mandible...

The replacement of one tooth using one implant involves a set of unique criteria for long-term success. Successful therapy should be based on long-term function and health of the adjacent tissues. Sections of this article examine these critical criteria that when working together can result in successful long-term tooth replacement.

There are several methods of regenerating the maxillary and mandibular ridge to achieve orthoalveolar form with bone grafting procedures, including block onlay grafting and guided bone regeneration. Traditionally, guided bone regeneration has focused on creating a space for bone regeneration to occur. The use of a formed titanium mesh to regenerate alveolar defects was popularized in the 1980s. With the advent of other adjuncts, such as resorbable membranes, and growth factors, such as recombinant human bone morphogenetic protein 2, the predictability of the procedure has increased and a wide variety of defects can be restored using this technology...

The edentulous posterior maxilla poses challenges to reconstruction. Posterior forces are great, yet bone quality and quantity are diminished. There is frequent loss of bone resulting from ridge resorption as well as sinus pneumatization. There are also advantages of placing implants in the posterior maxilla compared with the anterior maxilla, such as improved hygiene, esthetics and phonetics, and biomechanical load distribution. This article will present strategies and techniques for improving implant support in the posterior maxilla through various grafting techniques...

The immune system has a vital role in the development, establishment, and progression of head and neck squamous cell carcinoma (HNSCC). Immune evasion of cancer cells leads to progression of HNSCC. An understanding of this mechanism provides the basis for improved therapies and outcomes for patients. Through the tumor's influence on the microenvironment, the immune system can be exploited to promote metastasis, angiogenesis, and growth. This article provides an overview of the interaction between immune infiltrating cells in the tumor microenvironment, and the immunologic principles related to HNSCC...

Nodal metastasis is the single most prognostic determinant in patients with oral squamous cell carcinoma (OSCC). Since its inception more than a century ago, the management of the neck has led to decreased surgical morbidity, with continued preservation of oncologic safety for OSCC. Nodal metastasis is the single most prognostic determinant in patients with OSCC. The decision for the extent of the neck dissection is tailored to tumor-specific characteristics, which dictate the probability and extent of nodal metastasis, including tumor size, location, histopathologic characteristics, and the presence or absence of clinical nodal disease...

Stavan Y Patel, Andrew T Meram, Dongsoo D Kim
Soft tissue reconstruction of head and neck ablative defects is a broad, challenging, and subjective topic. The authors outline goals to keep in mind when deciding on a primary reconstructive option for defects created by oncologic resection. Factors considered in local, regional, and distant flap selection are discussed. Based on the goals of reconstruction and factors involved in flap selection, a defect-based reconstructive algorithm is developed to help choose the ideal reconstructive option. The authors also discuss indications, pearls, pitfalls, and challenges in the harvest and inset of commonly used soft tissue flaps for head and neck reconstructive surgery...
