When the elderly are missing half of their teeth, if they are often referred to as half missing, similar to the full denture restoration method, they can consider a movable denture restoration with a half denture. However, the conventional restoration of half missing teeth is more difficult and relatively less effective than a full denture. This is because when restoring missing hemifacial teeth, it is necessary to achieve a good natural bite with the opposing teeth, and the remaining teeth in the opposing jaw are often elongated, misaligned and worn out, which makes it difficult to form a good bite with the opposing teeth of the hemifacial denture. In addition to this, the great pressure on the edentulous jaw and the hemiprosthesis from the natural will further lead to instability of the conventional hemiprosthesis, gum swelling and pain, and accelerated alveolar bone resorption. Therefore, it is recommended that patients who are financially well off may opt for implant hemi-denture restorations. A hemi-denture with implant support can significantly improve the defects of conventional restorations and increase patient satisfaction with the denture. If half of the maxillary and mandibular dentition is missing, both removable and implant prosthetic restorations may be considered. Similar to the reasons for poor restoration of missing halves, the results of removable denture restorations are affected by the poor retention stability of the denture and therefore the fabrication of the denture requires a period of patient adaptation before it can be used properly. If a patient cannot accept a removable denture, an implant restoration is the best option for the patient.
