I need 2 dental implants for both central incisors I only have 1 central incisor and my other 1 is a Maryland bridge attached to my other 1 which has been in place for about 15years but due to darkened tooth root and receding gum on my own tooth it needs extracting but I need a bone graft but can't afford it aswel has implants but I'm looking to get both lateral incisors removed to get immediate implants with 4 unit bridge,would this work ok?
