tissue in a two stage process the surgeon sutures tissue over the implant waits several months for the bone to adhere to the implant opens the tissue attaches abutment 36 to abutment implant interface 28 and attaches crown 38 to abutment 36 bone tissue apposition surface 42 and soft tissue apposition surface 44 maintain bone and soft tissue attachment levels and facilitate prevention of peri implant infections which occur due to increased peri implant pocket depths frequently observed with the prior art implant designs therefore implants constructed according to the present invention increase the longevity of the implant and improve the aesthetic appearance of the restoration referring to fig5 a and 5b abutment implant interface 28 has substantially planar upper surface 25 which is approximately 90 u00b0 to the longitudinal axis of shaft 26 and connecting means 46 for connecting abutment 36 fig3 and 4 to abutment implant interface 28 connecting means 46 is well known in the art and includes but is not limited to internal hex external hex standard hex tall hex wide hex or camlog in an alternative embodiment of the present invention as shown in fig6 8 abutment implant interface 48 has at least its edges contoured to approximate the contours of the alveolar bone thereby defining a contoured upper surface 50 fig8 surrounding connecting means 46 also provided in this alternative embodiment is abutment 52 which has lower contoured surface 54 configured to substantially mate with contoured upper surface 50 the upper and lower contoured surfaces provide additional lateral support between abutment 52 and abutment implant interface 48 additionally contoured upper surface 48 of this alternative embodiment results in a narrower depth between.
