口腔种植学（Implant Dentistry）

28 calificaciones

口腔种植学是口腔教育中较新的学科。虽然现在我们都有共识，种植⽛相关的理论知识，⽆论是治疗⽅案的规划，还是后期的随访和维护，对于每⼀个职业⽛医都⾮常重要。然⽽，在当下全球的口腔医学本科培养体系中，它的覆盖程度还远远落后于其重要性。在此背景下，香港大学口腔医学院联合⾹港⼤学的线上教育专业团队，历时⼀年有余，设计并制作了这门为期五周的⽹络公开课，旨在传播以循证医学为基础的，客观、全⾯的⽛种植学相关知识。这门课程⾯向全球，双语教学，完全免费。学员将在20 多位全球领先的种植学专家的带领下，完成五个模块，系统地学习⽛种植学。

Greetings from Hong Kong!

It has been an amazing start in the course

and I thank you for your enthusiasm throughout this week.

I and our course tutors have met over a thousand learners

on the discussion forum in the past few days.

I had enjoyed lively and constructive discussions

on various topics in Implant Dentistry with you,

and indeed, I have got quite a few ideas

for future research from your comments.

I know we’ve got some very quick learners in this course.

For those of you who have already post questions

and comments for Weeks 2 to 5,

or have post a mission statement (in Week 2),

solved the implant case (Weeks 2 to 5),

please stay tuned with us in the upcoming weeks.

We will continue to have even more lively discussions

when more of your online peers and instructors join

the interaction in the discussion forum.

Now as we have reached the end of Week 1,

I take the opportunity to sum up

some of the interesting topics

that were discussed in the forum.

One of the questions that consistently emerged

in this week’s discussions was about

connecting teeth with implants under the same prosthesis.

As we discussed, given the many significant functional

and anatomical differences between teeth and implants,

many people wondered if it is really a good idea

to join them under the same fixed dental prosthesis.

Let's see what the evidence says for this discussion.

We would like you to take a look

at some papers we have compiled,

which will help you better understand

the long-term survival and success rates

of different types of implant supported

or conventional fixed dental prosthesis.

This will also be discussed in more detail in Module 4.

As you can see in the first table,

the 10-year survival rate of

conventional fixed dental prostheses on teeth is around 90%,

while that of an implant supported bridge is very close.

With regards to tooth-implant supported bridge however,

the survival rate drops significantly to 77%.

This is still a high survival rate for 10 years,

but of course, not as high as in prosthesis supported

solely by either implants or natural teeth.

Furthermore, looking at the complication rates

that have been observed for the two types of reconstructions,

we see similar rates for most of the problems,

apart from the problem of the intrusion

of the abutment tooth, which is not uncommon

when we mix teeth and implants.

So, conclusively, is it a good idea

to mix teeth and implants?

Well, as the evidence shows,

it is certainly not our first option today.

Nevertheless, it remains a valid possibility,

which can be considered in special cases when the anatomy

and also the patient's needs would favor such a solution.

Another point that our learners discussed

was the sulcus around teeth and implants.

The attachment of the peri-implant tissues

and the height of the biological width

do not appear to be influenced

by the gingival biotype of the patient.

Also, as of today, no surgical technique, surface,

or device has been able to

predictably manipulate the soft tissue attachment around implants.

As you heard from Professor Ivanovski,

we have made tremendous progress in osseointegration,

by improving the implant surfaces.

But when it comes to the soft tissue attachment, guess what?

We are at the same point we were

with the first Brånemark implants.

So make a note there, those of you

who are after a cool research project,

an improvement in the soft tissue attachment

could be a significant breakthrough in implant dentistry.

Many people wondered if we could actually create

an equally shallow healthy sulcus around

implants as we have around teeth.

I think this is possible but it

greatly depends on the local anatomy.

So if we are dealing with an area of

the alveolar ridge that is relatively flat,

as it might be in the posterior maxilla or mandible,

the peri-implant sulcus can be relatively shallow,

especially around tissue level implants.

However, in the aesthetic zone,

this is where a deep sulcus is almost inevitable.

And in most cases, the better the aesthetics we achieve,

the deeper the sulcus that we will have to create.

Finally, some questions that caught our attention.

Can we create an implant coating that could

offer shock absorption like a periodontal ligament?

Or is the pattern of bone resorption

when we remove implants the same as when we remove teeth?

Excellent questions, for which

we have no answers at present.

So maybe this could be some exciting

research projects for some of you?

I’m looking forward to continue

our exciting interaction in Week 2

and thank you all for your enthusiasm and participation.
