Overdenture: Maxillary One-Piece Transitional O-Ring Implant and Three Standard Bicon implants and their Restoration with an Implant Retained Overdenture
This case demonstrates the placement of a one-piece transitional o-ring implant and its restoration as well as that of three two-piece implants with a metal framed implant retained overdenture without palatal coverage.

43. Registration material being injected onto wax rim.


44. Recording occlusal relationships.


45. Digital image being taken of shade guide against a black plastic background to facilitate the fabrication of an aesthetic overdenture.


46. Pink plastic housing being inserted onto transitional one-piece o-ring implant to facilitate stabilization of prosthesis.


47. Denture adhesive being added to provide retention for clinical evaluation.


48. Preliminary prosthesis being inserted for clinical evaluation.


49. Clinical evaluation of prosthesis.


50. Confirming measurements.


51. Clinical evaluation of prosthesis.


52. View of processed denture.


53. Separating medium being injected around abutments.


54. Rubber dam aprons being placed over abutments to prevent extraneous acrylic from locking around the abutments.


55. Pink plastic housing being inserted onto o-ring abutment, since titanium housing would be seen through thin flange of the denture.


56. Titanium housing being inserted onto o-ring abutment.


57. Separating medium being applied to denture to prevent inadvertent reline of the prosthesis during the housing pick up into the denture.


58. Denture being inserted to confirm appropriateness of its fit over the housings.


59. Denture being inserted to confirm appropriateness of its fit over the housings.


60. Acrylic being injected into denture for the retention of the housings.


61. Acrylic being injected around housings for retention of the housings.


62. Patient clenching on two cotton rolls until the acrylic around the housings is completely polymerized to assure that the denture will be EVENLY TISSUE BORNE.
