Dental implants have been advocated as the treatment of choice for missing teeth and tooth replacements. Scientific evidence demonstrates their high success rates and therefore their clinical applicability. However, in some circumstances due to premature posterior tooth loss leading to severe sinus pneumatisation or a congenitally missed tooth causing alveolar bone collapse, implant placement can still remain challenging for clinicians. These circumstances could be present in one surgical target area at the same time, thus increasing treatment complexity. In such cases, available options such as short implants, ridge splitting, and internal and crestal sinus lifts have been proposed to minimise treatment cost and time, as well as co-morbidities but preserve treatment success rates.
