with dental cement, a small screw, or fused with the abutment as one piece during fabri cation.Dental implants, in the same l h6j way, can also be used to retain a multiple too th dental j prosthesis either in the form of a fixed bridge or removable dentures. implant sup l h6j ported bl 6j ridge (or fixed denture) is l ja group of teeth secured to dental jl implants so the prosthetic cannot be removed by the user. Bridges typically connect to more than one implan l h6j t and may also connect to teeth as anchor points. Typically l 6j the number eh6j iof teeth will outnumber the anchor points with the teeth that are directly over the implants referred to as abutments and those between abutmen ts referred to as pontics. Im eh6j iplant supported bridges attach to implant abutments in the same way as a single tooth implant replacement. A fixed bridge may replace as few as two teeth (also known as a fixe d partial denture) and may extend l h6j to replace an entire arch of teeth (also known as a fixed full dentu re). In bothl 6j cases, the prosthesis is said to be f l eh6j ixed because it cannot be remol 6j ved by the denture wearer.[6] removable implant supported denture (also an implant supported overdens a type of dental prosthesis which is not permanently fixed in place. The dental prosthesis can be disconnected from the i mplant abutments with finger pressure by the wearer. To enable this, the abutment is shaped as eh6j i a small co nnector (a button, ball, bar or magnet) which can b l h6j e connected to analogoul 6j s adapters in the underside of the dental prosthesis. l 6j Facial prosthetics, used to correct facial deformities from cancer treatment or i c procedures, such as sinus lifts or gingival grafts, are sometimes required to recreate ideal bone l h6j and gingiva. The final prosthetic can be either fixed, where a person cannot remove the denture or teeth from their mouth o r removable, where they can remove the prosthetic. Inl 6j each case an abutment is attached to the implant fixture. Where the prosthetic is fixed, the crown, bridge or denture is fixed to the ab eh6j iutment with eitl jher lag screws or d ental cel jment. Where t eh6j ihe prosth l h6j etic is removl jable, a corresponding adapt l h6j er is placed in the prosthetic so that the The risks and complications related to implant therapy are divided into those that occur during surgery (such as excessive bleeding or nerve injury), those that occur in the first six months (such as infectio
