Zygomatic implant placement has been shown to be a reliable method to reconstruct severe maxillary atrophy and maxillary deficiency defects. The placement of zygomatic implants is more complex and more challenging than conventional oral implant placement especially in the quad approach. The application of navigation surgery in complex craniomaxillofacial procedures has become very helpful in transferring the surgical plan to the patient and avoiding adjacent anatomic injuries. This article shows the feasibility of real-time navigation in zygomatic implant placement via building a clear workflow...

Maxillary all-on-four implant reconstruction requires training beyond normal dental implant training. It conjoins technical surgical acumen, anatomic and complex spatial relationship understanding, thorough awareness of dental prosthodontic principles, and excellent patient management skills. Acquisition of appropriate training to the level of competence in an era of greater patient expectations and increased vigilance for patient safety and overall quality of care is limited. Repeated purposeful practice in performing complex psychomotor tasks is of paramount importance in achieving competence...

Displaced dental implants in the mandible may constitute a clinical challenge for both physicians and patients. The complex anatomy of the floor of the mouth, together with its subsequent violation due to implant displacement makes implant allocation and retrieval a challenging procedure. Computerized navigation surgery (CNS) has been previously described and proved successful in various surgical modalities. In this article, the authors present a recommended protocol for the use of CNS for the retrieval of displaced dental implants in the mandible and describe the workflow through the stages of diagnosis, preoperative surgical planning, and the surgical procedure...

REVIEW
R John Tannyhill, Ole T Jensen
Mandibular all-on-4 implant reconstruction techniques are less complex than maxillary but more complex than routine dental implant surgery, requiring advanced technical skills, deeper understanding of prosthodontic principles, and more complex surgical planning. Surgical simulation may assist experienced surgeons seeking to acquire new skills through increased planning ability, improved intraspecialty communication, and enhanced technical competence. Achieving competence is different for the trainee devoted to the learning process and the practicing surgeon with limited time and balancing other roles and responsibilities...

REVIEW
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...

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...

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...

Immediate loading of maxillary denture prostheses in the context of severe bone atrophy is complicated by posterior implant placement, sometimes requiring a complex surgical approach as zygomatic or pterygoid implants. To overcome this complexity, the authors developed an extra-long (20-24 mm) 24-degree angulated platform. It was tested on 33 patients, with 24 patients immediately loaded (72.7%) for a total of 115 implants (46% nasal). All delayed loading implants osseointegrated. Eight bilateral and six unilateral sinus grafts were performed...

Guided bone regeneration is an effective alternative for the reconstruction of atrophic ridges. Adequate flap management together with immobilization of the barrier membrane and graft are crucial to ensure successful regenerative radiographic and clinical outcomes. Moreover, tension-free flap closure should be accomplished to guarantee to maximize the effectiveness of guided bone regeneration.

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.
