Implant dentistry has seen a surge in popularity in recent years, due in part to the advancements in materials and surgical techniques. One of the critical aspects of successful implant placement is the creation of a secure and stable implant-bone interface, known as the crestal bone to implant contact (CBC). The CBC plays a crucial role in determining the long-term success of the implant, as it influences the stability of the implant and helps to prevent peri-implantitis.
The CBC is influenced by various factors, including surgical techniques, such as under-drilling and over-drilling. Under-drilling is a surgical technique where the implant site is prepared by creating a shallow trench that is slightly smaller than the implant, while over-drilling is a technique where the implant site is prepared by creating a hole that is slightly larger than the implant.
Under-drilling has become increasingly popular in recent years due to the increased primary stability that it provides. It helps to reduce the implant-bone interface and increase the mechanical interlock between the implant and the bone. This results in improved initial stability, reduced implant movement, and decreased risk of implant failure. However, under-drilling can also result in less initial bone-to-implant contact, which may negatively impact the long-term stability of the implant.
Over-drilling, on the other hand, has been shown to increase the initial CBC and create a more intimate implant-bone interface. This results in improved long-term stability and reduced risk of implant failure. However, over-drilling can also lead to increased implant movement, reduced primary stability, and increased implant failure.
In conclusion, both under-drilling and over-drilling have their benefits and limitations when it comes to the CBC and overall implant success. GP Implants Ltd provides a range of implant options to suit various surgical techniques. As with all surgical procedures, it is essential to carefully consider the risks and benefits and consult with a qualified implant dentist.
