Clinical experience, misunderstood concepts and frequently asked questions. Notes from many years of practice.
Medentika is a German maker of implants and abutments, founded in 2005 and owned by the Straumann Group. Its longest published implant follow-up is 12 months.
Nobel Biocare implants are made in Sweden by a Swiss-headquartered, US-owned company. On the TiUnite surface, ten-year implant-level survival was 95.14%.
MegaGen implants are made in Daegu, South Korea, with a grade 4 titanium body; 57 AnyRidge implants showed 98.1% survival over four years.
A deep bite is an overlap of the upper front teeth beyond the normal 1 to 2 mm; braces correct it by intrusion or levelling, aligners mainly in milder cases.
Replacing an old crown or veneer means removing it, checking for decay and making a new one; a dark line at the gumline, chipping or movement signal it.
The ridge keeps shrinking under a denture: 20 human studies found horizontal bone loss of 29 to 63 percent within six months of extraction.
A cohort of 162 zirconia single crowns reported failure-free survival of 93.1% for monolithic and 96.2% for partially veneered designs. Where zirconia leads.
A systematic review of 13 randomised trials found denture adhesives significantly improve retention and stability, with low to moderate certainty of evidence.
Five-year survival was 96.8% for monolithic zirconia and 97.3% for veneered zirconia in a meta-analysis of 64 studies. Here is how translucency compares.
