Geometry of the bone present can make implant placement challenging. This can be especially true in the anterior, where the angle of the ridge requires a different trajectory than that of the prosthetic axis that will be used during restoration.1 Both the maxillary and mandibular ridge tip to the facial aspect, requiring implant placement that is not vertical in position. This can become more complicated in a site that is either edentulous or undergoing significant periodontal changes to the bone present, as the facial aspect is lost first, shifting the trajectory of the available bone present.

The presence of sufficient bone volume is one of the most important criteria for successful osseointegration of implants,1 wherefore restoration of atrophied edentulous maxillae poses a great dilemma for the surgeon and restorative dentist. Sinus bone grafting to build new bone for implant anchorage in atrophied jaws entails multiple surgical interventions and has varying implant success rates, high potential for donor site morbidity and increased surgical costs.2, 3 A major breakthrough came when Brånemark first used custom-designed, longer implants inserted into the zygomatic bone in support of a craniofacial prosthesis in the 1980s.4 When used in the treatment of maxillary atrophy,5, 6 zygomatic implants present a graftless alternative.

Although the final goal of the endodontic therapy is to provide symptom-free functional teeth with healthy periapical tissue long term,1 the severely damaged structure sometimes does not allow the clinician to succeed in the pursuit of saving natural teeth. In these scenarios, alternative treatments such as crown lengthening, autogenous transplantation or even implant placement should be considered with the objective of maintaining occlusal stability and functionality.2, 3

Long, narrow root canals are a real challenge even for renowned endodontic experts. Just like a good navigation system in your car, modern endodontic motors help you keep track on the long and winding road to the apex. In the following case, the clever co-pilot navigated the author safely through the treatment of a necrosis in tooth #47—indicating “traffic jams” as well as recommended “stops”.

The patient reported on in this article was referred to my dental office by his general dental practitioner. There was a large cavity and symptoms of irreversible pulpitis in tooth #26. The 38-year-old male patient had reported to his general dental practitioner with the complaint of toothache in the left upper jaw. The maxillary left first molar was diagnosed as the cause of his complaint. The cavity had been partially prepared, and the mesial wall temporarily restored.

The aim of this article is to present a case of single-tooth prosthetic restoration in the aesthetic zone step by step. The patient was referred to our clinic with a fractured root of tooth #11 (Fig. 1). The cone beam computed tomography (CBCT) analysis confirmed the fracture and revealed external resorption of the root from the vestibular side (Fig. 2). The tooth had to be extracted, and it was decided to follow immediate implant placement with a temporary aesthetic implant restoration. The immediate implant placement was planned with short-term non-occlusal loading.

As the profession of orthodontics evolves, we as orthodontists must continue to create solutions in order to offer a variety of treatment options to our patients. Furthermore, with the current challenges to our profession, we can elevate ourselves and our practices by expanding our possibilities and incorporating new treatment modalities. We must remember as specialists in orthodontics and craniofacial orthopaedics, every treatment plan should consider an orthodontic component, as well as an orthopaedic component, even in the non-growing patient. Remember, the word “orthopaedic” by definition means the correction of deformities of bones or muscles.1

KATANA Zirconia Block (Fig. 1) has hardly any features in common with the zirconia that was so popular in dental laboratories two decades ago and was used as a framework material. In many cases, this innovative zirconia serves as a functionally and aesthetically sensible alternative to high-strength glass-ceramics. Its flexural strength is higher than that of lithium disilicate, its translucency on a level with the low-translucency variant of the ceramic and its surface—if smoothly polished—antagonist-friendly, causing low wear.
