However mechanical issues such as fractures and screw loosening led to the development of the internal connection or 'internal hex' implants as they are known. By placing an implant at or beneath bone level it allows for a more stable and long-term implant-to-abutment connection. Over time, this became the unofficial 'industry standard'. However despite their obvious benefits, internal hex implants are not without their problems. Given the fact that the best scenario for any implant-based restoration is to place the implant into bone and ensure it remains in place with no movement, manufacturing difficulties have demonstrated that internal hex implants don't always solve this issue.   *Why?*   In most cases when the abutment is fitted there is often a tiny disparity between the fit of the internal hex platform and the connection, meaning that the implant is vulnerable to tiny micro movements when normal lateral forces are applied. Over time, these movements can cause bone loss which in turn causes the implant to become loose.   But that's not all...   In addition, as lateral forces are applied in the form of biting or chewing, a pumping effect occurs. When this happens any micro-gaps can open up further between the parts. As the gap increases it creates the ideal home for the invasion and colonization of bacteria.   ## **Conical connections: solving the micro-movement conundrum **  There is however an answer to this 'moving' issue in the form of conical connections. With an internal hex platform, flat on flat parts are milled so that they clear internally. Ultimately this means the distinct possibility of more space (gaps) between where the implant and abutment connect, plus an increasing chance of micro-movements and micro-gapping.   Alternatively, conical connections create a wedging effect which offers a better press fit connection as the sides spread. Ultimately a rigid and better seal between the implant and abutment means greater implant stability and therefore a stronger unit. In addition, any gapping is minimal so any kind of pumping effect is virtually eliminated. Clearly this is good news for both patient and dentist alike.    ## **So just how popular are conical connections?**  As clinical research is increasing and implant technology is improving, there has been a rise in interest in conical connections over the last few years. In a recent survey for example, an [industry leading laboratory published findings](http://glidewelldental.com/education/inclusive-dental-implant-magazine/volume-6-issue-4/trends-in-implant-dentistry-conical-implant-connections/)which took a look at custom abutment prescriptions over a 4 year period.... They found that the need for conical connections had increased by ***286%*** between 2011 and 2015. It's suggested that factors driving this trend are an increased knowledge about how conical connections can aid implant success but in addition, [other studies](https://www.ncbi.nlm.nih.gov/pubmed/26096450) have shown that conical prosthetic connections with platform switching ability, can also help to increase the amount of soft tissue surrounding the implant, preserve the crestal bone, and ultimately, provide all-round, greater implant stability.   ## **So where does this leave dentists?**  It's understandable that opting to use internal hex implant/abutment connections across numerous restorations presents a level of familiarity that many dentists are comfortable with. After all, if the clinician has experienced many successful outcomes, why change something that in all honesty, probably doesn't need changing?   The fact is that making the switch from internal hex connections to [conical connections](https://www.adin-implants.com/product/touareg-closefit/) is incredibly simple and doesn't require any change in the way that dentists work. But more than that, as suggested in a wide range of clinical trials, the considerable benefits and advantages for the patient means that conical connection implants have to be worth considering.
