Case Study 1
Complex Multidisciplinary Full Mouth Rehabilitation
Rehabilitation involving endodontic retreatment, orthodontics, guided implant placements and restorations with PFM crowns and bridges
A 61-year-old gentleman presented seeking to restore his missing teeth with dental implants and to restore his broken teeth. He had received extensive dental treatment in the past including root canal therapy and dental crowns, however, he complained of continual pain from his root treated teeth and repeated breakages of his restorations.
Careful examination revealed apical periodontitis associated with multiple teeth as well as defective restorations and fractures on the existing dentition. Occlusally, mesial drifting of the 36 and 46 precludes sufficient space for dental implant placement. In addition, as the 23 was in a cross-bite position, a mutually protective occlusion cannot be achieved with the pre-existing occlusal scheme.
The complexity of this case warranted a collaborative multidisciplinary approach to achieve the best long-term results. Root canal therapy and retreatment were performed on 17, 16, 15, 14, 11 and 26 by an endodontist. Extraction of hopeless teeth 12 and 37, followed by ridge preservation of the 12 site was performed by a periodontist. Orthodontic treatment was then carried out to reverse the cross-bite at the 23 position in order to attain canine guidance. In addition, the 36 was mesialised whilst the 47 was up-righted to allow for implant placement at the 46 site. Three Southern ex-hex implants were placed at the 24, 25 and 46 positions, followed by conventional fixed-prosthodontic restorative work to restore his dentition.

Case Study 2
Restoration of Tooth Wear with a Minimally Invasive Approach
Indirect composite resin adhesive restorations
The patient was unhappy with her smile and complained of cold sensitivity, especially when she consumes cold beverages and whilst brushing her teeth.
Lifestyle factors such as excessive acidic food consumption, as well as aggressive toothbrushing were identified and addressed.
A diagnostic wax-up was performed conforming to the existing OVD. This was transferred and refined intraorally to ensure a harmonious smile and incisal plane.
Minimal tooth preparations such as enamel bevelling were performed to assist with restorative-enamel margin shade integration. Subsequently, indirect composite resin restorations were fabricated in accordance to the diagnostic wax up and were bonded onto the tooth structure using a resin cement. Canine guidance was restored to reduce the risk of premature attrition related wear of the posterior teeth. The patient was then placed on a strict maintenance schedule to ensure long-term stability of her oral condition.
Case Study 3
Full-Arch Implant-Supported Fixed Dental Prosthesis
A partially edentulous patient with failing dentition
The patient presented complaining of a loose maxillary partial denture and poor aesthetics. In addition, he also reported having great difficulty chewing due to his missing teeth. He reported to have been a heavy smoker but had quit 5 years ago. He also reported to have lost his teeth due to periodontitis in the past.
An initial stabilisation phase was carried out by a periodontist to evaluate the prognosis of his remaining dentition. At the conclusion it was deemed all his remaining upper teeth had an extremely poor prognosis whilst the lower dentition could be kept and maintained with regular SPTs. Appropriate treatment options were presented, and informed consent was obtained. The patient elected to proceed with an implant-retained and -supported fixed dental prosthesis for his upper jaw and a tooth- and implant- supported removable dental prosthesis for the lower arch. The diagnostic phase involved maxillary and mandibular diagnostic set-up and fabrication of a radiographic guide for dual-scan CBCT acquisition and implant planning.
Six regular platform implants were placed in the maxilla and one on the lower left mandible. A delayed loading protocol was adopted due to insufficient primary stability of around 25Ncm. After osseointegration, provisional prostheses were made to ensure optimal speech, mastication and access to oral hygiene. A milled titanium bar was designed according to the provisional prosthesis with individual lithium discilicate crowns fabricated and cemented onto the bar to cater for future servicing needs if required. Pink composites were used to mimic the gingiva and to ensure the best possible aesthetical outcome. A cobalt chrome mandibular removable prosthesis was made and the implant at the 36 site was connected to a Locator abutment to assist in the retention and support of the prosthesis, effectively eliminating potential issues of a free-end saddle prosthesis.
