The named clinic is an author affiliation. The study patients were not established as patients treated at that clinic.
Key takeaways
- A randomized university study compared two ways of connecting crowns to back-tooth implants.
- The intermediate-abutment group had a lower reported mean bone-loss measurement. This is not a success-rate comparison.
- The patients were recruited at UIC. Teknon appears as an affiliation of coauthor Federico Hernandez-Alfaro, not as the treatment site.
- A clinic assessment is needed to determine suitability, treatment stages and a current quotation.
The question this study addresses
The study examines whether an intermediate connector between an implant and its crown affects the surrounding bone.
- The situation
- Replacement of missing back teeth with two implants.
- The treatment
- Fully guided placement of bone-level implants, followed by fixed restorations.
What this evidence cannot establish
- The 30 participants form a published study cohort, not Bookimed patient cases.
- Results do not establish that Teknon treated these participants or that one method is appropriate for every patient.
Two published treatment groups
12 patients · Published study group
Direct implant connection
- Indication
- Missing posterior teeth requiring implant-supported restoration.
- Treatment
- The restoration connected directly to the implant platform.
This randomized group included 12 participants with 24 implants.
The restoration connected directly to the implant platform.
Reported mean marginal bone loss
1.17 ± 0.35 mm
12 patients · Study group
Plus/minus as reported by the source
Reported group mean across the observation period; follow-up lasted two years.
Limits of this evidence
- The measurement concerns bone loss, not implant survival or patient satisfaction.
- No group-specific complication rate is presented in this summary.
For a clinic assessment
- Ask the clinic which dental scans and treatment history are needed for assessment.
18 patients · Published study group
Intermediate abutment connection
- Indication
- Missing posterior teeth requiring implant-supported restoration.
- Treatment
- An intermediate abutment remained in place for the restorative workflow.
This randomized group included 18 participants with 36 implants.
An intermediate abutment remained in place for the restorative workflow.
Reported mean marginal bone loss
0.83 ± 0.25 mm
18 patients · Study group
Plus/minus as reported by the source
Reported group mean across the observation period; follow-up lasted two years.
Limits of this evidence
- The measurement concerns bone loss, not implant survival or patient satisfaction.
- No group-specific complication rate is presented in this summary.
For a clinic assessment
- Ask the clinic which dental scans and treatment history are needed for assessment.
How to interpret the result
The reported between-group comparison favored intermediate abutments (p = 0.001). Individual suitability requires clinical assessment.
Limitations and unknowns
- These findings do not provide an individualized forecast.
- The paper reports measurements over several visits; the mean shown here is not labeled as a result from one specific appointment.
- Costs, travel requirements and a current Teknon package were not established by this research.
What to clarify in your treatment plan
Use the study as a question for the treating dentist, rather than as a treatment prescription. Confirm the proposed implant, connector, crown and follow-up arrangements before booking.
Centro Médico Teknon: current clinic profile
- The linked profile provides current Bookimed clinic information and review counts.
- The study lists Centro Médico Teknon as a coauthor affiliation; recruitment took place at UIC.
Federico Hernandez Alfaro: current professional profile
Federico Hernandez Alfaro
Oral and maxillofacial surgeon
- Federico Hernandez-Alfaro is a coauthor of the paper and has a current Bookimed profile linked to Teknon. Authorship does not mean he personally treated every study participant.
Safety and aftercare questions
General patient guidance, provided separately from the case evidence. Follow your treating team's instructions.
Possible side effects
- Soreness, swelling, bruising or bleeding can follow implant placement.
Ask your dental team how to manage these symptoms and follow its individual instructions.
Recovery and aftercare
- Follow-up care remains important after the procedure.
Agree the review schedule and who will provide continuing dental care after you return home.
Suitability and cautions
- Implant suitability depends on oral health and available bone.
Request an assessment of gum health, bone support and relevant medical history before selecting a technique.
When to contact the clinic
- Bleeding that does not stop needs urgent attention.
Seek urgent local medical care for persistent bleeding; contact the treating team for other concerns about recovery.
Request a current clinic quotation
Ask Centro Médico Teknon for an individual dental implant assessment and an itemized quotation.
Confirm the number of implants, crown and abutment specifications, additional procedures, appointments and aftercare. No current package price is inferred from this study.
Ask the clinic for a current, itemized quotation. Published evidence does not establish package inclusions or a current price.
Questions before booking
Were these patients treated at Teknon?
The publication states that recruitment was at the Dental University Clinic of UIC. Teknon is a coauthor affiliation. This page does not present the cohort as Teknon patient cases.
Does lower bone loss mean a higher implant success rate?
These are different outcomes. The displayed measurements concern marginal bone loss; they are not presented as implant-survival percentages.
Is the research result a current clinic offer?
No. The study is clinical evidence. Use the clinic assessment link to obtain current availability, inclusions and a quotation.
