Periodontitis has caused the loss of a front tooth, necessitating prompt dental restoration. After the loss of a front tooth due to periodontitis, it's important first to check whether there has been any resorption of the alveolar bone. If the alveolar bone is normal and shows no signs of inflammatory resorption, dental restoration can proceed directly. If the condition of the alveolar bone is favorable, an implant can be considered. During implantation, a single tooth is implanted, allowing for direct restoration with a porcelain crown without the need to grind the adjacent healthy teeth. However, if opting for a bridge, it may be necessary to grind the adjacent healthy teeth to support the bridge, meaning that at least three teeth would need to be involved in the restoration.
